Description

Partial almanac collection system

Technical field

The present invention relates generally to GPS (" GPS ").Especially, the present invention relates to be used to collect from the almanac collection system of segmentation year calendar (almanac) information of gps satellite.

Background technology

The worldwide utilization of wireless device (being also referred to as " mobile device ") increases just fast, and this wireless device comprises for example twoway radio, portable television, personal digital assistant (" PDA "), cell phone (being also referred to as " aerophone ", " wireless telephone ", " mobile phone ", cellular phone and/or " transfer table "), satelline radio receiver and global position system (" SATPS ") be such as the U.S. (" U.S. ") GPS (" GPS ") (being also referred to as NAVSTAR).Along with the increase of the number of using wireless device, the function that wireless service provider provided (fatures) number also increases, the integrated also increase of these wireless devices in other products equally.

Since the early stage U.S. Department of Defense seventies in 20th century (" DoD ") Joint Program Office (" JPO ") was created NAVSTAR, the many civilian reference of the new technology related with GPS had appearred utilizing.As example, these new technologies comprise that the permission user determines the personal GPS receiver of the position that it is gone up at the earth's surface and the numerous communication networks that utilize the gps clock benchmark to move, such as CDMA (" DCMA ") and time division multiple access (TDMA) (" TDMA ") cellular network.Result as these new technologies, existence is to the growing demand of following mobile device, and this mobile device can in case of emergency send its position, incorporates positional information into communication facilities, visitor, children and old man are also followed the tracks of in the location, and the safety guarantee that valuable property is provided.

Usually, gps system is typically based on the navigational system of satellite (being also referred to as " spacecraft " or " SV ").The example of GPS includes but not limited to the U.S. (" U.S. ") navy navigation satel-lite system (NNSS) (" NNSS ") (being also referred to as TRANSIT), LORAN (rowland), Shoran (Shoran), Decca (decometer), TACAN (Tacan), NAVSTAR (navigation satellite timing and ranging), is called the Russian homologue of the NAVSTAR of GLONASS (Global Navigation Satellite System), such as the West Europe GPS in any future of " Galileo " plan that proposes.

NAVSTAR GPS (hereinafter referred is " GPS ") researches and develops as military systems for the needs that satisfy US military; But US Congress indicated DoD to promote that also GPS's is civilian afterwards.The result is that GPS is can be by the dual-purpose system of mechanism of U.S. government (such as the military) and both visits among the people now.At GPS Theory and Practice, Fifth ed., revised edition by Hofmann-Wellenhof, Lichtenegger and Collins, Springer-Verlag Wien New York has described this gps system in 2001, and this article is all incorporated into wherein by reference.

Typically, the application of GPS comprises tellurian accurate location of sign and synchronous cellular phone network such as the communication network of military communication network and for example CDMA and TDMA type system.In addition, provide the order of the mobile telephone network in the cellular telephone subscribers place within 50 feet along with US Congress sends by Federal Communications Committee (" FCC ") in case of emergency (being commonly referred to as " strengthening 911 " service or " E911 "), the place of just adopting GPS to be used for many cellular application is determined and is synchronous.

Usually, gps satellite array (being commonly referred to as " a GPS group of stars ") sends the information of the time encoding of pin-point accuracy, and this information allows the GPS receiver to calculate it about on earth the latitude and the place of the height above sea level on longitude and the sea level.Design GPS provides basic navigation system with the precision within about 100 meters and even provides higher precision (will select availability " SA " to be set to ON) for army and other authorized user for the non-user of army.

GPS typically comprises three main system segments: space, control and user.The space segment of GPS be comprise to tellurian GPS receiver send highly accurate timing information transmitter, an empty satellite group of stars on earth along orbital flight.At present, a GPS group of stars of being realized comprises that 21 main operation satellites add 3 movable backup satellites.These satellites are arranged in 6 tracks, and each track comprises three or four satellites.Orbit plane and equator form 55 ° angle.The empty on earth height place that is similar to 10,898 nautical miles (20200 kms) of these satellites is along orbital flight, and the orbital period of each satellite is similar to 12 hours.

As example, in NAVSTAR, each satellite along orbital flight comprises 4 High Precision Automatic clocks (two rubidiums (rubidium), two caesiums (cesium)).These automatic clocks are provided for generating the accurate timing pulse of the unique binary code (being also referred to as pseudorandom " PRN-sign indicating number " or pseudo noise " PN-sign indicating number ") that is sent to the earth.Particular satellite in this PRN-sign indicating number sign GPS group of stars.Satellite also sends the set of number information encoded, and it comprises the two class orbit parameters that are called locus almanac data and ephemeris (ephemeris) data, that be used for determining satellite.

The accurate track of almanac data (being also referred to as " ephemeris ") definition satellite.Almanac data is indicated at any given time satellite wherein, and can identify its place according to the satellite ground track of accurate latitude and longitude tolerance.Information in the almanac data is encoded and is going out from satellite transmission, with the accurate expression of satellite position that earth top is provided at any given time.Usually, current almanac data enough is used for determining in the rank of current SA the place of several meters in space or tens meters.Ground control station per hour upgrades an almanac data to guarantee precision.Yet after about two hours, the precision of almanac data begins to reduce.

Almanac data is the subclass of almanac data.Almanac data comprises the lower accuracy information about all satellite places in the group of stars.Almanac data comprises few relatively parameter and generally is enough to determine in the space several kilometers place.Each gps satellite is with cycle of ten two five (" 12.5 ") minute and all gps satellites in a GPS group of stars are broadcasted this almanac data.So,, can obtain the almanac data of every other satellite in the track by only following the tracks of a satellite.This almanac data upgraded once and is useful always in about some months in every several days.Because the life-span that it is long relatively, the GPS receiver of having cut out above several hrs utilizes this almanac data to determine which gps satellite is visible (in-view) usually.Yet year calendar and almanac data are all only effective in the time in finite quantity.Like this, aging along with year calendar and almanac data is based on the satellite place of this information out of true more and more, unless in time upgrade this data with proper spacing.

Almanac data comprises the position of determining satellite at any time in the coordinate system of land and three data sets that velocity vector can be used.These three data sets comprise almanac data (as previously mentioned), THE MEDOC and precise ephemeris.These data are different and available in real time or available at (after the fact) afterwards on precision.Usually, the purpose of almanac data is to provide less precise information so that receiver satellite acquisition or be used for for example plan target of the calculating of visibility chart for the user.Almanac data was updated once and as the part of satellite message and broadcast in per at least six days.Almanac data in the satellite message comprises satellite clock calibration item and the orbit parameter that is used for all satellites necessarily.The GPS almanac data is by Arlington, the NavTech Seminars ﹠amp of Va.; Be described among reprint " GPS Interface Control Document ICD-GPS-200 " for the " NAVSTARGPS Space Segment and Navigation User Interfaces " in February nineteen ninety-five that NavTech Book and Software Store publishes, be incorporated in here by reference.

In the typical operation example, when the GPS receiver is opened (generally being called " cold start-up ") or when the length that surpasses several hours is treated to wake up the writ attitude, the GPS receiver will scan the GPS frequency spectrum to obtain from the gps signal of available gps satellite transmission first.In case obtained gps signal, the GPS receiver will be then from GPS almanac data, almanac data and the clock alignment information of a gps satellite download GPS group of stars that is obtained.In case downloaded almanac data, gps satellite will scan the GPS frequency spectrum then to obtain available (i.e. " the as seen ") gps satellite shown in the almanac data.Ideally, given grace time also supposes that the environmental aspect around the GPS receiver allows the GPS receiver to obtain two or three additional visible gps satellites, and then the GPS receiver is from these three to four satellite receiving ranges and timing informations and calculate its position on earth.

Unfortunately, under a lot of the application, especially under indoor or limited sky can be seen this attitude, time and environmental aspect can limit the ability of GPS receiver download GPS almanac data.Usually be described by primary positioning time (Time-to-First-Fix: " TTFF ") value with the problem of time correlation.If the TTFF value is high, then the GPS receiver will have limited application, can not determine its initial place because it will spend the long time.

As an example, in wireless or cellular phone application, have the mobile phone of integrated GPS receiver or personal digital assistant (" PDA ") and may have to before calling out, wait for about 12.5 minutes of GPS receiver download GPS year calendar (suppose the visible satellite that is necessary can observable ecotopia situation).This uses for majority is unacceptable.

In cellular phone application, consider to require cell phone in the E911 urgent call, its positional information to be sent to emergency personnel's E911 order that this restriction is unacceptable especially.If the user finds that themselves is in the emergency condition, and the cell phone of the GPS that has shuts down or is in the long writ attitude for the treatment of, then these users are before carrying out user locations being sent to emergency personnel's urgent call, to generally have at first wait for about 12.5 minutes, to keep continuously uninterrupted satellite visibility (because the common strong signal of needs of GPS receiver obtains year calendar and/or almanac data reliably).In typical urban or in the environment that blocks naturally, this wait will be longer than 12.5 minutes, because this environmental aspect makes that to obtain first satellite more difficult.Should notice that this is unacceptable especially under life-and-death situation.

The scheme of the time quantum that reduction download almanac data in the past is required has been included in the year calendar (for example almanac data of factory's installation) of some kinds of the middle storage of storage unit (for example ROM (read-only memory) " ROM ") of GPS receiver.Usually, utilize this almanac data of storing in advance to reduce TTFF under the cold start.

In this scheme, this cold start general since related with satellite position uncertain and this store the aging of year calendar in advance and still have the long relatively TTFF time.In case obtained first anchor point (fix), this GPS receiver can be then from the almanac data of this satellite down loading updating that obtains and upgrade ROM (or random access memory " RAM ") and be used for using in the future.Yet this scheme still requires this GPS receiver to receive the almanac data (promptly receiving " fresh " copy of almanac data) that upgrades from the satellite that is used for obtaining future.Receiving the almanac data that upgrades will still need very large time quantum, and this will influence the performance of GPS receiver.

Thereby, exist overcoming needs previous described problem, that can obtain the system of almanac information with effective means more.

In response to these problems, developed subplan for mobile phone, its for for example obtain, the purpose of location calculations and/or sensitivity improving is by providing auxiliary data to help the GPS receiver from communication module (being also referred to as " call processor " or " CP ").Some examples of these subplans comprise the U.S. (" the U.S. ") patent 6433734 that is entitled as " Method and apparatus for determiningtime for GPS receivers " of authorizing inventor Krasner on August 13rd, 2002, authorized the United States Patent (USP) 6421002 that is entitled as " GPS receriver utilizing a communication link " of inventor Krasner on July 16th, 2002, authorized the United States Patent (USP) 6411254 that is entitled as " Satellitepositioning reference system and method " of inventor Moeglein etc. on June 25th, 2002, authorized the United States Patent (USP) 6400314 that is entitled as " GPS receiver utilizing a communication link " of inventor Krasner on June 4th, 2002, authorize the United States Patent (USP) 6313786 that is entitled as " Methodand apparatus for measurement processing of satellite positioning system (SPS) signals " of inventor Sheynblat etc. November 6 calendar year 2001, authorize the United States Patent (USP) 6259399 that is entitled as " GPSreceivers and garments containing GPS receivers and methods for using these GPSreceivers " of inventor Krasner July 10 calendar year 2001, authorize the United States Patent (USP) 6215441 that is entitled as " Satellite positioning reference system and method " of inventor Moeglein etc. April 10 calendar year 2001, authorize the United States Patent (USP) 6208290 that is entitled as " GPS receiver utilizing acommunication link " of inventor Krasner March 27 calendar year 2001, authorize the United States Patent (USP) 6185427 that is entitled as " Distributed satellite position system processing and applicationnetwork " of inventor Krasner etc. February 6 calendar year 2001, authorized the United States Patent (USP) 6150980 that is entitled as " Method and apparatus for determining time for GPS receivers " of inventor Krasner on November 21st, 2000, authorized the United States Patent (USP) 6133874 that is entitled as " Method and apparatusfor acquiring satellite positioning system signals " of inventor Krasner on October 17th, 2000, authorized the United States Patent (USP) 6064336 that is entitled as " GPS receiver utilizing a communicationlink " of inventor Krasner on May 16th, 2000, authorized the United States Patent (USP) 5945944 that is entitled as " Method and apparatus for determining time for GPS receivers " of inventor Krasner on August 31st, 1999, authorized the United States Patent (USP) 5825327 that is entitled as " GPS receiver utilizinga communication link " of inventor Krasner on November 24th, 1998, authorized the United States Patent (USP) 5825327 described systems that are entitled as " GPS receivers and garments containing GPS receivers andmethods for using these GPS receivers " of inventor Krasner on October 20th, 1998, these patents are merged in the present invention by reference.Unfortunately, normally cellular network (promptly for example the cellular platform of TDMA, GSM, CDMA etc.) and the dealer's special use of subplan in these wireless networks, and provide by the geographical positioning service station that is positioned at this cellular network (Geolocation Server Station).As a result, the GPS receiver in the mobile phone (being also referred to as " transfer table " or " MS ") usually must with the geographical positioning service station compatibility of this cellular network.

But, the also not realization of many network assistance systems, and for the network assistance system that has realized, they have typically incorporated the geographical positioning service station that utilizes incompatible each other geographical positioning service station agreement into.Thereby, also exist for allowing the GPS receiver to be independent of the needs of geographical positioning service station agreement with many geographical positioning services station operated system.

In Fig. 5, the demonstration that shows the independent wireless movable positioning system framework 500 of agreement realizes.In Fig. 5, framework 500 can comprise mobile device 506, base station 508, wireless network infrastructure 510, geographical positioning service station 512, GPS reference receiver 514 and optional final user 516.Mobile device 506 and GPS reference receiver 514 receive gps signal via

signalling channel

504 and 502 from a gps satellite group of stars 226 respectively.

Mobile device 506 can comprise call processor 520, GPS module 522 and agreement stand-alone interface (being called " PI2 " here) 524.Each of call processor 520 and GPS module 522 can be in independent semi-conductor chip or the functional unit of realizing in a common semiconductor chip or small pieces.PI2524 is the interface that allows GPS module 522 512 reception auxiliary datas from the geographical positioning service station, and does not require the identical agreement of agreement that GPS module 522 is utilized and geographical positioning service station 512 is utilized.So PI2 524 makes GPS module 522 can avoid the specific implementation of the multi-protocols at different geographical positioning services station.PI2 524 can be the RS232 link, via the logic interfacing of the memory shared of software data structure or other types are electric and/or logic interfacing.

In the operation, each geo-location agreement can realize that this transducer is the standalone protocol that GPS module 522 is used with geographical positioning service station 512 protocol conversions via the transducer among the PI2 524.This allows along with mobile device 506 switches to another kind of wireless communication standard from a kind of wireless communication standard, and realize the seamless workability of geo-localisation information, receive auxiliary datas and send positions or other geo-location result's mode to geographical positioning service station 512 from call processor 520 thereby change mobile device 506.The result, because it is the agreement that GPS module 522 is utilized that PI2 524 can move freely the GPS information conversion at the geographical positioning service station 512 of the communication system that user's (not shown) of equipment 506 subscribes in the future, so each unique geographical location protocol (for example IS-817, IS-801 etc.) of all different air interfaces of utilizing in all parts of the world can be provided by GPS equipment 506, and need not to reset or reconfigure this GPS module 522.The example of PI2 524 can include but not limited to by the SiRF scientific ﹠ technical corporation exploitation of San Jose and the auxiliary independent interoperability interface (" AI3 ") that has.

Those skilled in the art should note existing for the different geographical localization criteria of dissimilar wireless network exploitations.As example, the interface 526 between base station 508 and the infrastructure 510 can be any air interface.This interface 526 is typically controlled by call processor 520 manufacturers.Usually, PI2 524 comprises two kinds of interfaces that are referred to as " F " interface (not shown) and " G " interface (not shown).

F interface as the client machine system interface between GPS module 522 and the call processor 520 is taken on Bootstrap Protocol, and this Bootstrap Protocol always exists and allows call processor 520 to select how will to help to be sent to the GPS module 522 of auxiliary encapsulated layer when operation.Call processor 520 is aloft selected between interface (for example interface 526 under the end-to-end system framework situation) or the G interface.F interface can be carried out following task: from GPS module 522 hardware managements (power on/cut off the power supply, reset) of call processor 520; If available, implicit satellite interface promptly sends the time of automatic network (or from call processor 520 real-time clocks) and the approximate location (if its existence generally lies in the network) of frequency transformation and mobile device 506 via call processor 520; Session open/close (promptly notify GPS module 522 opened/close air interface to connect); And in dual mode mobile device 506, which air interface is notice GPS module 522 opened, and notifies GPS module 522 to use thus and where organizes the next and SLS dialogue of geo-location air interface protocol.

Different with F interface, utilize G interface the 508 GPS supplementarys that receive to be sent to GPS module 522 from the base station.Owing to have many existing geo-location agreements usually, thus G interface can be designed to can be on a large scale geo-location standard and independently using on the air interface, be unique promptly for using air interface.But PI2 524 can be embodied as the simplification of applied geography localization criteria.

In the operation, call processor 520 sends to GPS module 522 by G interface with the position request information and the network-assist information of PI2 form.Conversely, GPS module 522 sends to call processor 520 by same interface with position result or Notice Of Discrepancy.Should notice that all geo-location agreements that comprise SAMPS, GSM and CDMA are operated under the reciprocation model.What base station 508 was only asked mobile device 506 beams back.In general, carry out interactive countermeasure height and depend on the knowledge that GPS module 522 is handled.

In addition, opposite with many protocol stack levels, the geo-location agreement is an application protocol, this means the semanteme (implication) of their processing messages.So they also not only are transported to the opposing party with data from a side, need not the error correction and the elimination that exchange or repeat in the TCP-IP storehouse.Like this, handle any entity of this agreement (for example judgement request some data) and need know what these data are used for, and in the implication (being that it need know what has taken place in GPS side) of cocommutative each parameter of this agreement.Like this, the implementer of geo-location agreement should be GPS " understanding (savvy) ".

So PI2 524 utilizes air interface finite state machine (" FSM ") (not shown).In general, this causes the current state that is in of FSM is to be forced by the current knowledge to the content of GPS storer (not shown), and causes sending a request message so that the judgement of some incomplete GPS information completely is built-in among the FSM self.

Like this, Fig. 6 shows the block diagram based on the CDMA mobile device 600 of IS-801 of utilizing FSM.Mobile device 600 comprises call processor 602 and GPS module 604.Call processor 602 comprises that air interface CP module 606, air interface protocol are to GPS module interface converter 608, GPS module data structure 610, GPS module air interface assembler/disassembler 612, GPS module/CP system message agreement assembler/disassembler 614 and GPS module interface module 616.GPS module 604 comprises CP interface module 618, PI2 interface module 620, PI2 data structure 622, CP system interface FSM 624 and GPS kernel 626.GPS kernel 626 receives gps signal via signalling channel 632 from a gps satellite group of stars 226, and air interface CP module 606 is carried out signal communication via signalling channel 630 and base station (not shown).

Figure 10 shows the example implementation with arbitrary example apparatus shown in Figure 2 202,204,206,208,210 and 212 similar integrated communicatons and gps system 1000.The integrated communicaton of Figure 10 and gps system 1000 will receive gps signals 1002 from the GPS group of stars 226 of Fig. 2, the base station towers 228 by Fig. 2 utilizes non-cellular communications networks (not shown) to receive the signal of communication 1004 of Figure 10 from the cell phone communication network (not shown) or by non-honeycomb tie point 230.Integrated communicaton and gps system 1000 can comprise communication module 1006 (such as call processor " CP "), carry out GPS kernel 1007 and partial almanac collection system (" PACS ") 1010 in the GPS module 1008 of signal communication with call processor 1006.

Call processor 1006 can be can with any communication equipment that carries out unidirectional or two-way communication such as the external communication network of cell phone communication network (not shown) or non-cellular radio or non-wireless network (not shown).The cell phone type example of communication module 1006 can comprise that by the Illinois cellular calls that the Motorola Inc. of Schaumberg produces is handled integrated scheduling and strengthened network (" iDEN ^TM"), the CDMA2000 that uses by the Qualcomm of the Sony-Ericson of the Nokia of Finland, Sweden, San Diego, CA ^The GSM/CDMA/TDMA/UMTS class communication facilities of 1X cake core group or any similar type that can communicate by letter with GPS module 1008.The example of non-cellular-telephone type communication facilities can comprise the SX45 GPS utility appliance of producing by the SA of Siemens, can with BlueTooth ^Any communication facilities of communication, based on the Wireless Fidelity (" Wi-Fi of IEEE 802.11 ^") network or other similar wireless networks.GPS module 1008 can comprise any GPS receiver that can communicate by letter with communication module 1006.GPS kernel 1007 is to receive from the gps signal of a gps satellite group of stars 226 and from the gps signal that is received to extract typical GPS functional block the GPS receiver of gps data.

PACS 1010 can comprise controller 1012, be used to store the memory devices 1014 such as nonvolatile memory and/or memory device of data, interface 1018 (such as above-mentioned PI2 interface) carries out the PACS communication bus 1016 of signal communication with controller 1012, memory device 1014, interface 1018, call processor 1006 and GPS module 1008.PACS 1010 can be integrated in (such as being integrated on the same IC semiconductor small pieces) in call processor 1006 or the GPS module 1008, perhaps can be the independent external unit in integrated communicaton and the gps system 1000.PACS 1010 also can be the independent external unit in integrated communicaton and gps system 1000 outsides, such as outside additional card or equipment.In addition, PACS 1010 can be integrated on the single integrated circuit semiconductor chip that comprises call processor 1006, GPS module 1008 and PACS1010.

Controller 1012 can be the controller of random processor type, comprise call processor 1006 processor (not shown), GPS module 1008 the processor (not shown) or can control how collect almanac datas and how with the ppu of collected data transfer to call processor 1006 by GPS module 1008.Controller 1012 can be microprocessor, digital signal processor (" DSP ") or application-specific IC (" ASIC ").Under the situation of microprocessor or DSP, can utilize the software (not shown) to control the operation of controller 1012.This software can reside in controller 1012, call processor 1006, the GPS module 1008, perhaps reside in the detachable memory (not shown), such as detachable memory disc (such as the medium of floppy disk, CDROM, DVD or other similar type) or the card (such as MemoryStick ^TM, CompactFlash ^TM, xD ^TM, SmartMedia ^TMPerhaps other similar mediums).

As the example of operation, PACS 1010 allows GPS modules 1008 to receive part from a GPS group of stars 226 (that is, segmentation or piecemeal) year calendar.In this way, integrated communicaton and gps system 1000 are unnecessary etc. is ready to use in the remarkable time quantum that GPS module 1008 is downloaded whole whole year calendars of almanac datas, keeps not interrupting continuously satellite visibility simultaneously.

The information (but when its become the time spent) that PACS 1010 allows GPS modules 1008 to receive almanac datas and each single satellite is provided for PACS 1010.PACS 1010 can receive the information such as year calendar week and time of arrival (" TOA ") from GPS module 1008, and year calendar week and TOA are associated with each satellite data that GPS module 1008 is provided.PACS 1010 compiles the satellite information that receives from GPS module 1008 then, and understands the freshness of each satellite in (keeps track of) year calendar.The result is, PACS 1010 can work to having the year calendar that following satellite mixes, and these satellites have different year calendar ephemeris and TOA information.

Usually, PACS 1010 controllers 1012 can be via the year calendar download session of 1016 startups of PACS communication bus and termination and GPS module 1008.PACS 1010 controllers 1012 can also determine whether it receives enough satellite informations to understand the state of each satellite the year calendar from GPS module 1008.Controller 1012 is stored in year calendar in the nonvolatile memory 1014 of PACS 1010 for using in the future via PACS communication bus 1016 then.PACS 1010 can be delivered to call processor 1006 and/or GPS module 1008 with almanac data via PACS communication bus 1016.

Usually, PACS 1010 can operate in two ways.First kind of mode can be described to poll and handle (promptly, method), wherein PACS 1010 downloads to GPS module 1008 demand staging year calendars in response to receiving the segmentation download request (if PACS 1010 is the equipment that separates with call processor 1006) from call processor 1006.PACS 1010 continues to propose periodic request collecting the year calendar state to GPS module 1008, till receiving (indicated as complete year calendar receiving flag) or PACS fully and finishing decision before the downloading fully of almanac data and close session with GPS module 1008.PACS 1010 is can be for multiple difference former thereby closed session with GPS module 1008 before almanac data is downloaded fully, described multiple different reasons comprise outage (that is, when the user turn-offs integrated communicaton and GPS equipment 1000), economize on electricity consider, received the complete year calendar that is used for call processor 1006 or because call processor 1006 queued sessions close with send call out or carry out with afoul another function of the opened session of GPS module 1010.

The second way can be described to non-polling method, and wherein PACS 1010 equally may be in response to receiving from the request of call processor 1006 and downloaded to GPS module 1008 demand staging year calendars equally.But in this case, controller 1012 is judged the request how GPS module 1008 will respond from call processor 1006.If GPS module 1008 receives the time that is enough to finish complete almanac collection, then PACS 1010 replys to call processor 1006: year calendar is downloaded and is stored in the storer 1014 fully.Close if PACS 1010 determines to carry out before GPS module 1008 can be downloaded complete year calendar with the session of GPS module 1008 for arbitrary reason, then PACS 1010 replys to call processor 1006: downloaded partial almanac.If environmental aspect change thereby GPS module only can be downloaded partial almanac when GPS module 1008 is just being collected almanac data, then PACS 1010 replys to call processor 1006 and has downloaded partial almanac.In addition, if PACS 1010 determine GPS modules 1008 call processor 1006 can not collect any almanac information in given time limit, then PACS 1010 replys to call processor 1006 and can not collect any almanac data.

Turn to the Figure 11 that shows process flow diagram 1100 now, process flow diagram 1100 illustrates the exemplary method of the PACS operation of poll and non-poll processing mode.In exemplary poll was handled, processing started from step 1102 and continues by deciding step 1104 to step 1106.In step 1106, call processor is opened the session with PACS, and in step 1108, call processor request PACS carries out from the segmentation year calendar of satellite (being also referred to as " spacecraft " or " SV ") and downloads then.In response, PACS carries out the download of segmentation year calendar in step 1110.Call processor then poll PACS to check whether downloaded complete year calendar.In deciding step 1112,, then handle proceeding to step 1114 and PACS and go through state with the perfect year and make to call processor and replying if downloaded complete year calendar.Call processor is closed with the session of PACS then in step 1116 and is handled 1118 and finish.

On the contrary, if do not download complete year calendar, then handle from deciding step 1112 and proceed to deciding step 1120.In deciding step 1120,, then handle 1118 and finish if call processor has been closed the session with PACS.

But,, then handle from deciding step 1120 and proceed to step 1122 if call processor is not closed the session with PACS.In step 1122, at the polling request of call processor, PACS makes to call processor with collected satellite almanac state and replying.Handle and to proceed to step 1124 then, call processor periodically poll PACS to collect the segmentation year calendar.PACS replys by downloading to make at each poll execution segmentation year calendar in step 1110, and handle repeating step 1112,1120,1122,1124 and 1110 till having downloaded complete year calendar or call processor and having closed session, in this case, handle via step 1114,1116 and 1118 or finish via step 1120 and 1118.

In exemplary non-poll was handled, processing started from step 1102 equally and continues by deciding step 1104 to step 1126.In step 1126, call processor is opened the session with PACS, and call processor request PACS execution is downloaded from the segmentation year calendar of satellite in step 1128.PACS carries out the segmentation year calendar and downloads in step 1130, and makes to call processor with collected year calendar state in step 1132 and replying.In step 1134, the state of call processor request year calendar, and in deciding step 1136, PACS determines the time that whether PACS receives is enough to finish complete year calendar download.Should be appreciated that call processor also can carry out same determining.

Be enough to finish the time that complete year calendar is downloaded if PACS receives really, then handle from deciding step 1136 and proceed to step 1138.In step 1138, PACS reports the state of complete year calendar to call processor, and call processor is closed session with PACS in step 1140 in response.PACS stores almanac data into storer (that is, memory device) then in step 1142, and sends affirmation in step 1144 to call processor then.Handle then and finish 1118.

Be not enough to finish the time of downloading fully if PACS receives really, then handle from deciding step 1136 and proceed to deciding step 1146.In deciding step 1146,, then handle and proceed to step 1148 if call processor was carried out the session shutoff operation before PACS downloads complete year calendar.In step 1148, the state that PACS downloads to call processor report section year calendar, call processor is closed session with PACS in step 1140 in response.PACS stores almanac data into storer (that is, memory device) then in step 1142, and sends affirmation in step 1144 to call processor then.Handle then and finish 1118.

On the contrary, if call processor is not carried out the session shutoff operation before PACS downloads complete year calendar, then handle from deciding step 1146 and proceed to deciding step 1150.In deciding step 1150, if call processor and/or PACS determine signal(l)ing condition so that PACS only collects the mode of partial almanac to be changed, then PACS in step 1148 to the state of call processor report section year calendar.In response, call processor is closed session with PACS in step 1140.PACS stores almanac data into storer (that is, memory device) then in step 1142, and sends affirmation in step 1144 to call processor then.Handle then and finish 1118.

Perhaps, if call processor and/or PACS determine that signal(l)ing condition does not have so that PACS only collects the mode of partial almanac to be changed, then handle and proceed to deciding step 1152.In deciding step 1152, if call processor and/or PACS determine call processor and/or PACS in determined certain time PACS can not collect whole year calendars, then handle proceeding to step 1154.In step 1154, PACS makes to call processor with the state of representing to collect year calendar and replying.In response, call processor is closed session with PACS in step 1140.PACS stores almanac data into storer (that is, memory device) then in step 1142, and sends affirmation in step 1144 to call processor then.Handle then and finish 1118.

Figure 12 shows the signal flow graph 1200 that PACS 1202 performed example polls are handled.In this exemplary process, call processor 1204 is downloaded to PACS 1202 demand staging year calendars.Call processor 1204 can be born the responsibility that proposes to collect the periodic request of year calendar states to PACS 1202, receives till state that complete year calendar downloads or call processor 1204 decisions close session before finishing complete year calendar up to call processor 1204.Usually, this processing can comprise: call processor 1204 open with the session of PACS 1202 (may by the PI2 interface), to the PACS request collect that segmentation satellite (" SV ") year calendar is downloaded, in a single day periodic polls PACS 1202 to be to collect the segmentation year calendar, to make PACS 1202 make with collected SV year calendar state at each polling request to reply and finish download fully and just make call processor 1204 close the session with PACS 1202.PACS 1202 stored almanac data into memory devices 1260 (such as flash memory) then before the session between PACS1202 and the call processor 1204 is closed.PACS 1202 can receive the indication from call processor 1204, it comprises operating parameter, such as, but not limited to, the expression that still will not provide any year calendar auxiliary will be provided for indication and the call processor 1204 of collecting satellite almanac when signal(l)ing condition is on certain level (such as greater than 28dB-Hertz).

As shown in figure 12, call processor 1204 sends session opening request 1206 via interface 1208 (such as the PI2 interface) to PACS1202.PACS 1202 sends the affirmation 1210 to session opening request 1206.Call processor 1204 sends segmentation year calendar request 1212 to PACS 1202 then.PACS 1202 is delivered to controller 1216 with the request 1214 of segmentation year calendar from interface 1208 then, and controller 1216 will ask 1218 to be delivered to the interior GPS kernel 1220 of GPS module (not shown) and to send affirmation 1222 to call processor 1204.

GPS kernel 1220 receives the gps signal 1224 from a GPS group of stars 1226 then.GPS kernel 1220 extracts the almanac data that received and the almanac data 1228 that is received is delivered to controller 1216 from the gps signal 1224 that is received.Controller 1216 is determined pseudo noise number (" PRN "), time of arrival (" TOA ") and number of weeks from almanac data then, and will comprise that via 1230 and 1232 the almanac data of PRN, TOA and number of weeks is delivered to call processor 1204 from PACS 1202.In response, call processor 1204 is via to the request of year calendar update mode request and propose periodic request 1234 to the segmentation year calendar.Should be appreciated that, GPS kernel 1220 receives the

gps signal

1224 and 1236 from a GPS group of stars 1226 consistently, and controller 1216 periodically asks 1238,1240 and 1242 and receive 1244,1246 and 1248 almanac datas from GPS kernel 1220.

Controller 1216 usefulness are transmitted the 1252 segmentation almanac datas 1250 to call processor 1204, are replied making from the periodic request to the segmentation year calendar of call processor 1204 from PACS 1202.Controller 1216 is managed the almanac data storehouse then and is applied any mixing year calendar and handles.Point at a time, in response to the collection that receives from PACS 1202 state or the expression PACS of complete year calendar can not collect the state of year calendar, call processor 1204 sends session turn-off request 1254 to PACS 1202.When call processor 1204 when PACS 1202 sends session turn-off request 1254, session turn-off request 1256 is passed to controller 1216.Controller 1216 transmits 1258 almanac datas then to storing memory 1260.Controller is made to call processor 1204 via the affirmation of 1262 and 1264 usefulness then and being replied.

Perhaps, in non-poll example process, call processor proposes the request that year calendar is downloaded (downloading such as the segmentation year calendar) to PACS.Report to the year calendar download state makes a determination PACS based on following sight then: 1) if PACS receives the time that is enough to finish complete almanac collection, then PACS will report the state that complete year calendar is downloaded; 2) under the situation that call processor was closed for any reason execution session before PACS finishes complete year calendar download, the state that PACS downloads the report section year calendar; 3) if just collecting at PACS and to last that signal(l)ing condition changes and PACS only can collect partial almanac year, PACS state that the report section year calendar is downloaded then; And 4) PACS will can not collect the state of year calendar to call processor report because PACS certain schedule time as for example not collecting year calendar (typically under the situation a little less than the signal) in 5 minutes.PACS stored almanac data into memory devices (such as flash memory) then before the session between PACS and the call processor is closed, send affirmation to call processor then.

As example, Figure 13 shows the signal flow graph 1300 that the PACS 1302 performed non-polls of example are handled.In this exemplary process, call processor 1304 starts with the session of PACS 1302 and to PACS 1302 request year calendars downloads (downloading such as the segmentation year calendar).PACS 1302 can receive the indication from call processor 1304, it comprises operating parameter, such as, but not limited to, the expression that still will not provide any year calendar auxiliary will be provided for indication and the call processor 1304 of collecting satellite almanac when signal(l)ing condition is on certain level (such as greater than 28dB-Hertz).PACS 1302 then with the request of confirming answering call processor 1304, beginning almanac collection, and make to call processor 1304 with the year calendar status message and to reply.Call processor 1304 is asked the year calendar update mode from PACS 1302 then via message request.PACS 1302 usefulness comprise that the year calendar status message of the almanac data of collecting for all satellites of year calendar PRN, TOA and year calendar number of weeks is made to the request of call processor 1304 and reply.PACS 1302 manages the almanac data storehouse then and applies any mixing year calendar and handles.Point at a time, call processor 1304 is closed conversation request and is closed session with PACS 1302 by sending.PACS1302 stores year calendar into memory devices 1360 (such as flash memory) then, and sends affirmation to call processor 1304.

As shown in figure 13, call processor 1304 sends session opening request 1306 via interface 1308 (such as the PI2 interface) to PACS1302.PACS 1302 sends the affirmation 1310 to session opening request 1306.Call processor 1304 sends year calendar request 1312 to PACS 1302 then.PACS 1302 is delivered to controller 1316 with year calendar request 1314 from interface 1308 then, and controller 1316 will be asked the 1318 GPS kernels 1320 that are delivered in the GPS module (not shown), and sends affirmation 1322 to call processor 1304.

GPS kernel 1320 receives the gps signal 1324 from a GPS group of stars 1326 then.GPS kernel 1320 extracts the almanac data that received and the almanac data 1328 that is received is delivered to controller 1316 from the gps signal 1324 that is received.Controller 1316 is determined the state that year calendar is downloaded then, and via 1330 and 1332 the almanac data state is delivered to call processor 1304 from PACS 1302.In response, call processor 1304 proposes year calendar request 1334.Should be appreciated that GPS kernel 1320 receives the

gps signal

1324 and 1336 from a GPS group of stars 1326 consistently, and controller 1316 periodically asks 1338,1340 and 1342 and receive 1344,1346 and 1348 almanac datas from GPS kernel 1320.
