Description

Positioning method, terminal and server

This application claims priority from a chinese patent application filed on 11.01.2017 under the name of "a method and apparatus for GPS positioning" with the application number 201710020365.4, which is incorporated herein by reference in its entirety.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a positioning method, a terminal, and a server.

Background

The Global Positioning System (GPS), which may be called a satellite Positioning System, is a technology for accurately Positioning any object by using satellites. The GPS can ensure that at least 4 satellites can be observed at any point on the earth at any time, so that the functions of navigation, positioning, time service and the like can be realized.

The GPS system comprises: a space part, a control part and a user part. The space part of the GPS is composed of 24 GPS working satellites, and each GPS working satellite sends out a satellite signal for navigation and positioning. The control part of the GPS is composed of a monitoring system which is distributed on the whole world and consists of a plurality of tracking stations, and the monitoring system is used for monitoring the working state of the satellite. The user part of the GPS consists of a GPS receiver, data processing software and corresponding user equipment, such as a computer meteorological instrument, etc., for receiving signals transmitted by GPS satellites and using these signals for positioning, etc.

In a conventional satellite positioning scheme, on a terminal such as a mobile phone or a wearable device product, a GPS receiver of the terminal is often required to poll and receive satellite signals, and after the satellite signals of the current and local area are acquired in real time, a processor of the terminal completes mapping on a map to realize positioning. It can be seen that the following disadvantages exist in the conventional satellite positioning scheme: on one hand, the positioning time depends on the performance of hardware equipment such as a terminal GPS receiver, a processor and the like; on the other hand, polling for satellite signals may require coverage of all satellite parameters, and may result in a longer time to accurately receive the satellite signals of the desired satellite, which may in turn result in a longer time to subsequently map or navigate using the satellite signals.

How to overcome the above drawbacks in the conventional satellite positioning scheme and improve user experience is a problem to be solved in the industry urgently.

These components may communicate over one or more communication buses or signal lines. These components may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits,

referring to fig. 2, the wireless communication unit 210 generally includes one or more devices allowing wireless communication between the terminal 200 and a wireless communication system, communication between the terminal 200 and another terminal, communication between the terminal 200 and an external server, and the like. Further, the wireless communication unit 210 generally includes one or more devices that connect the terminal 200 to one or more networks. As shown in fig. 2, for example, the wireless communication unit 210 may include a wireless cellular communication module 211 (operable to provide a long-range wireless communication function), a wireless internet module 212, a short-range wireless communication module 213 (operable to provide a short-range wireless communication function), and the like.

The GPS unit 220 may receive satellite signals (radio signals) transmitted from satellites in the GPS through an antenna, and from these satellite signals, the GPS unit 220 may generate information that is usable for various applications. For example, each satellite in the GPS often broadcasts its own ephemeris data (ephemeris information) repeatedly according to a fixed period, based on the principle of satellite positioning technology, the GPS unit 220 may determine the position information (e.g., longitude/latitude information) of the current position of the terminal 200 after accurately knowing the satellite clock (clock) and orbit information of 3 to 4 satellites in the GPS, and these information may be used for applications such as navigation and map mapping as needed.

The input unit 230 is generally configured to receive various types of input information such as audio, video, tactile input, and the like. The input unit 230 may include, for example, a user input unit 231 (e.g., a touch screen, a touch key, a push key, a mechanical key, a soft key, etc.), an audio input unit 232 (e.g., a microphone), a camera 233, and the like. The user input unit 231 may be used to allow a user to input information; the audio input unit 232 may be used to input an audio signal; the camera 233 may be used to obtain images or video. Data is obtained by the input unit 230 and may be analyzed and processed by the processing unit 280 according to device parameters, user commands, and combinations thereof.

The output unit 240 is generally configured to output various types of information such as audio, video, tactile output, and the like. The output unit 240 may have, for example, a display unit 241, an audio output unit 242, and the like. The display unit 241 may have an interlayer structure or an integral structure with a touch sensor for facilitating a touch screen, or the like.

Among other things, the touch screen may provide an input interface and an output interface between the terminal 200 and a user. On one hand, the user input unit 231 can be used for receiving user input, such as collecting contact or non-contact operation of the user on or near the user input unit, and driving the corresponding connection device according to a preset program; the display unit 241 is alternatively available for displaying visual output to the user, which may include graphics, text, icons, video, and any combination thereof, such as displaying information input by the user, information provided to the user, and various menus of the terminal 200, etc.

The sensing unit 250 is generally configured to sense internal information of the terminal, a surrounding environment of the terminal, user information, etc., and may be implemented by one or more sensors. The sensing unit 250 may include sensors such as a touch sensor, an acceleration sensor, a magnetic sensor, a gyro sensor, a motion sensor, a pressure sensor, an RGB sensor, an Infrared (IR) sensor, a finger scan sensor, an ultrasonic sensor, an optical sensor, a battery ammeter, an environmental sensor (e.g., a barometer, a hygrometer, a thermometer, a radiation detection sensor, a light sensor, a heat sensor, a gas sensor, etc.), and a chemical sensor (e.g., an electronic nose, a biometric sensor, etc.), for example. The terminal 200 may be configured to acquire signals from and/or transmit signals to one or more sensors of the sensing unit 250.

The interface unit 260 serves as an interface with various types of external terminals that can be coupled to the terminal 200. The interface unit 260 may include, for example, any of a wired or wireless port, an external power supply port, a wired or wireless data port, a memory card port, a port for connecting a terminal having an identification module, an audio Input/Output (I/O) port, a video I/O port, a headphone port, and the like. In some cases, the terminal 200 may perform a control function associated with the connected external terminal in response to the external terminal being connected to the interface unit 260.

The storage unit 270 is typically implemented to store data to support various functions or features of the terminal 200. For example, the storage unit 270 may be configured to store application programs executed in the terminal 200, data or instructions for the operation of the terminal 200, and the like. Some of these applications may be downloaded from an external server via wireless communication. Other applications may be installed in the terminal 200 at the time of manufacture or shipment, and these applications typically correspond to basic functions of the terminal 200 (e.g., receiving calls, placing calls, receiving messages, sending messages, etc.). It is common that application programs are stored in the storage unit 270, installed in the terminal 200, and executed by the processing unit 280 to perform operations with respect to the terminal 200.

The processing unit 280 is a control center of the terminal 200, connects various parts of the entire terminal using various interfaces and lines, and performs various functions of the terminal 200 and processes data by operating or executing software programs and/or devices stored in the storage unit 270 and calling data stored in the storage unit 270, thereby performing overall monitoring of the terminal. The processing unit 280 may process signals, data, information, etc. input or output via various components shown in fig. 2, or activate an application program stored in the storage unit 270, provide or process information or functions interacting with a user. For example, the processing unit 280 may control some or all of the components of the terminal 200 according to the execution of application programs that have been stored in the storage unit 270.

The power supply unit 290 may be configured to receive external power or provide internal power to supply appropriate power required for the terminal 200 to operate the elements and components included therein. The power supply may be logically coupled to the processing unit 280 through a power management system to manage charging, discharging, and power consumption functions through the power management system. The power supply unit 290 may include a battery, and the battery may be configured to be embedded in the terminal body or configured to be detachable from the terminal body.

It should be understood that the terminal structure shown in fig. 2 is not intended to be limiting and may include more or fewer components than shown, or some components may be combined, some components may be split, or a different arrangement of components.

For example, terminals such as cell phones, tablet computers, notebook computers, etc., often have the same or more functions and components than the terminal 200 shown in fig. 2; for another example, wearable, small-sized terminals, such as smart watches, smart bracelets, smart glasses, head-mounted displays (HMDs), tend to have fewer functions and components than the terminal 200 shown in fig. 2 due to their limited size. For example, the wireless communication unit in a wearable terminal often does not include a wireless cellular communication module, but rather includes a short-range wireless communication module.

Generally, wearable terminals may be used to exchange data or collaborate with terminals in their vicinity. As shown in fig. 1, the short-range communication module that the terminal 103 can possess is sensed or recognized by the short-range communication module according to the corresponding communication protocol in the terminal 102 that is close enough to it, and when the terminal 102 senses that the terminal 103 is an authenticated terminal that can communicate with the terminal 102, the terminal 102 can transmit data processed in the terminal 102 to the terminal 103 via the short-range communication module, so that the user of the terminal 103 can use the data processed in the terminal 102 on the terminal 103. For example, when the terminal 102 runs a music playing application, the user can listen to music using the terminal 103.

Based on the terminal 200 shown in fig. 2, it can be seen that the terminal can receive satellite signals through a GPS unit configured therein. In a conventional satellite positioning scheme, a GPS unit of a terminal often polls to receive satellite signals, and thus all satellite parameters may need to be covered, which results in a long time required to accurately receive the satellite signals of a desired satellite, and relatively high performance requirements on hardware devices such as the GPS unit and a processing unit of the terminal. In order to overcome the defects in the traditional satellite positioning scheme, the terminal can quickly acquire satellite data corresponding to a target area in a target time period, and user experience is improved, the positioning scheme is provided.

Specifically, the positioning scheme provided by the embodiment of the present application can be applied to a communication system including a terminal and a server, such as the communication system 100 shown in fig. 1; specifically, the terminal and the server may be respectively configured with a functional module for implementing the positioning scheme provided in the embodiment of the present application, and the functional module for executing the process may be implemented by hardware, software programming, or a combination of hardware and software, for example, server-side software and client-side software for implementing the positioning scheme provided in the embodiment of the present application may be respectively configured on the server 101, the terminal 102, and the terminal 104 in the communication system 100.

The following describes a positioning method flow provided by the embodiment of the present application with reference to fig. 3 based on the communication system architecture shown in fig. 1.

Fig. 3 shows a flowchart of a positioning method according to an embodiment of the present application. In particular, the process may be performed by the first terminal, such as the functional modules configured on the terminal 102 and the terminal 104 in fig. 1 to implement the process shown in fig. 3.

As shown in fig. 3, the process includes the following steps:

step 301: dividing the map into M partitions according to a set rule, and determining that satellite data corresponding to the N partitions in the map in a set time range in the future needs to be acquired by the first terminal, wherein M, N is a positive integer, and M is greater than or equal to N.

Specifically, in some practical scenarios, the set rule for dividing the map into M partitions may be to divide the map according to longitude and/or latitude. For example, the setting rule may be that longitude and latitude lines for dividing the map are determined according to the set longitude interval and latitude interval, and then each geographical area divided by the longitude and latitude lines on the map is used as each partition. It can be seen that the partitions obtained by the setting rule can be conveniently corresponding to the orbit data of the satellite, thereby being convenient for calculating the satellite data corresponding to each partition for each partition.

In some practical scenarios, the setting rule may be to divide the map according to administrative regions. For example, the sub-area may be each country on a map, or more precisely, may be an administrative region (such as province, district, county, etc.) obtained by each country performing administrative division on the prefecture. It can be seen that the partition obtained by the setting rule has the advantages of better meeting the user habit and being beneficial to improving the user experience.

It should be understood that there are other ways to set the rules for dividing the map into the partitions, and this application will not be listed here.

Specifically, the M partitions obtained by dividing the map according to the set rule may be identified by a number, a label, or a coordinate, which is not limited in the present application.

Specifically, the first terminal may determine N partitions from M partitions obtained by dividing the map, and further determine that satellite data corresponding to the N partitions needs to be acquired within a set time range in the future.

For example, the first terminal may determine 1 partition from the M partitions in the map, where N is equal to 1, and further determine that satellite data corresponding to the partition within a set time range in the future needs to be acquired; for another example, the first terminal may also determine 2 or more partitions from the M partitions in the map, and further determine that satellite data corresponding to the multiple partitions within a set time range in the future needs to be acquired.

As an example, fig. 4 is a schematic diagram illustrating N partitions in a map in a positioning method according to some embodiments of the present application. As shown in fig. 4, the map is divided into 25 partitions of 5 × 5 according to the set rule, where M is equal to 25, and assuming that the 25 partitions are identified by numbers 1 to 25, the first terminal determines, from the 25 partitions, that satellite data corresponding to the 4 partitions of which the numbers are 7, 8, 17, and 25 in order within one set time range in the future needs to be acquired, and the area filled with oblique lines as shown in fig. 4, that is, the area corresponds to N is equal to 4.

Specifically, in a possible implementation scenario, the first terminal may receive an instruction for acquiring satellite data, so as to determine that satellite data corresponding to N partitions in a map within a set time range needs to be acquired according to the received instruction; the command for acquiring the satellite data can carry information for setting a time range and N partitions.

For example, based on the communication system example shown in fig. 1, the terminal 102 may be configured with functional modules for executing the process shown in fig. 3, and provide a menu for acquiring future satellite data to the User of the terminal 102 through a User Interface (UI).

Specifically, the menu may include a UI control for providing a user to directly confirm that satellite data in the future needs to be acquired, which is equivalent to confirm to acquire satellite data corresponding to a default partition within a default time range, where the default time may be preconfigured, and for the purpose of improving user experience, the default time may be a time length of one day or longer starting from a current time, and the default partition may also be N preconfigured partitions, for example, a partition on a map corresponding to a geographical area where the user is frequently located that is preset by the user, or the default partition may also be provided for the user to modify settings, and the like;

or, the menu may also specifically include a UI control for providing a user to select or input (including voice or typing manner, etc.) a future time range, which is equivalent to confirming to acquire satellite data corresponding to the default partition within the time range required by the user; or, the menu may also include a UI control for providing a user to select a partition or input the information of the partition required, which is equivalent to confirming to acquire satellite data corresponding to N partitions required by the user within a default time range; or, the menu may also specifically include a UI control for providing the user to select or input a future time range, and a UI control for providing the user to select a partition or input the required partition information, which is equivalent to confirming to acquire satellite data corresponding to N partitions within the time range required by the user.

Furthermore, the user of the terminal 102 may perform operations on the menu as required, for example, the user of the terminal 102 may select a time range and N partitions corresponding to satellite data to be acquired according to a geographical range in which the user may be located in a future set range, the user operation is converted into an instruction in the terminal 102 and transmitted to the processor of the terminal 102, and the processor of the terminal 102 may further determine, based on the instruction, that satellite data corresponding to the N partitions in the set time range needs to be acquired.

After determining that satellite data corresponding to N partitions in the map within the set time range needs to be acquired through step 301, the first terminal may generate a request message for acquiring the satellite data, and may further perform step 302 in the flow shown in fig. 3.

Step 302: a first terminal sends a request message to a server; wherein, the request message carries indication information for setting time range and N partitions.

Specifically, the server may be configured to receive and process a request message for acquiring satellite data from any terminal or authenticated terminal, and may be configured to return satellite data requested by the server to a corresponding terminal.

For example, still based on the communication system example shown in fig. 1, the server 101 may be configured with a function module to receive and process a request message for acquiring satellite data from any terminal or authenticated terminal, and may be configured with a function module to return satellite data requested by the corresponding terminal. For example, the server 101 may receive a request message transmitted from the terminal 102 with which a communication connection is established, and may return satellite data requested by the server to the terminal 102.

Specifically, after receiving the request message sent by the first terminal in step 301, the server may parse the request message, and determine a set time range corresponding to the satellite data required by the terminal and N partitions in the map.

In a possible implementation scenario, after determining a set time range and N partitions corresponding to satellite data required by a terminal, a server may calculate satellite data corresponding to the N partitions within the set time range according to historical satellite data, so as to return a response message carrying the satellite data corresponding to the N partitions within the set time range to a first terminal.

Specifically, the historical satellite data may be satellite data issued by each satellite in the GPS, which is acquired by the server and stored in the server.

Since each satellite in the GPS generally broadcasts real-time satellite data according to a fixed period, in some practical scenarios, a GPS unit configured to receive a satellite signal may be configured on the server to receive the satellite data broadcasted by the satellite in real time, and the satellite data may be stored in a storage unit of the server after being received, and the processing unit of the server may perform the above calculation process by reading historical satellite data stored in the storage unit. The server can also set a valid period for the stored satellite data at each time in history, so as to ensure the accuracy of the calculation result, for example, the valid period can be set to one day;

or, in some practical scenarios, the server may be configured with a communication interface for communicating with a network device storing satellite data, and the server may directly obtain historical satellite data from the network device through the communication interface. Specifically, the server may obtain historical satellite data within a preset time period before taking the current time as an endpoint, where the preset time period may be a day or longer time period; and so on.

Further, after the server acquires the historical satellite data, satellite data corresponding to the N partitions in the set time range can be calculated according to a preset algorithm. For example, the server may determine the distribution of each satellite from the historical satellite data, and further calculate the satellite data of each satellite passing through the partition in the future within the set time range for each partition in the N partitions.

Specifically, the satellite data of each satellite passing through the partition in the set time range may include an Identifier (ID), orbit data, clock data, and the like of each satellite passing through the partition in the set time range; it can be seen that the satellite data described above can be used to instruct the terminal to more efficiently search for satellite signals.

In some practical scenarios, in consideration of improving user experience, the server may also obtain historical satellite data according to a set period, calculate satellite data corresponding to each partition on the map within a default time range, and store the calculation result in the storage unit of the server, for example, satellite data corresponding to each partition may be bound and stored with each partition, and then, after the server receives the request message sent by the first terminal, if it is determined that the set time range is within the default time range, the server may directly read the stored calculation result and return the calculation result to the first terminal, so as to accelerate the response speed.

Specifically, the server may further store map data, and further return the map data of the partition bound with the satellite data while returning the satellite data required by the first terminal to the first terminal.

Through the above process, the server may return a response message carrying satellite data corresponding to the N partitions within the set time range to the first terminal. Further, the first terminal may perform step 303 in the flow shown in fig. 3.

Step 303: and the first terminal receives a response message returned by the server.

Specifically, after receiving the response message returned by the server, the first terminal may obtain satellite data corresponding to the N partitions within the required set time range by analyzing the response message.

Further, after the first terminal acquires satellite data corresponding to N partitions within a set time range, the acquired satellite data may be stored in a storage unit of the first terminal, and further, within the set time range, the first terminal may read the satellite data corresponding to the N partitions within the set time range stored in the storage unit, and search satellite signals using the satellite data; by the method, the first terminal can perform satellite search based on the acquired future satellite data pre-calculated by the server, and the satellite search method has pertinence compared with the current polling satellite search method, so that the defects that accurate satellite signals are searched and the time required for positioning is long due to current polling satellite search can be overcome;

especially, under the condition that the first terminal does not have the capability of communicating with the base station or the first terminal is offline, and the GPS unit of the first terminal cannot obtain the auxiliary positioning information, the conventional polling satellite searching scheme needs to search about 32 pseudo random noise codes (PRNs) (equivalent to the satellite signals), and through the above process shown in fig. 3, the first terminal can accurately position by searching 4 to 5 PRNs, which greatly shortens the time.

Further, after the first terminal stores the acquired satellite data corresponding to the N partitions within the set time range in the storage unit of the first terminal, if it is detected that the second terminal establishes a communication connection with the first terminal, the first terminal may transmit the satellite data corresponding to the N partitions within the set time range to the second terminal, so that the second terminal can search for a satellite signal using the satellite data within the set time range.

For example, still based on the example of the communication system shown in fig. 1, after the terminal 102 acquires satellite data corresponding to N partitions within the set time range through the above-mentioned communication process with the server 101, since it is detected that the terminal 103 establishes a communication connection with the terminal, the terminal 102 may transmit the above-mentioned satellite data acquired by the terminal to the terminal 103, so that the terminal 103 may also search for satellite signals using the above-mentioned satellite data within the set time range.

Specifically, after the terminal 103 is connected to the terminal 102, the terminal 102 may first confirm whether satellite data can be transmitted thereto; for example, the terminal 102 may authenticate the validity of the transmission to the terminal 103, which will not be described in detail in this application.

In particular, the second terminal may be connected to the first terminal via a short-range wireless communication technology, which is described above, and may specifically include bluetooth, Wi-Fi, infrared data transmission, and the like.

Further, the second terminal may specifically be a terminal having a short-range wireless communication function, and not having a function of communicating with the base station and/or a function of communicating with the server. For example, a bluetooth bracelet and a bluetooth watch, which only have a GPS unit, are wearable devices and are limited in size and often do not have a function of communicating with a base station. When the second terminal searches satellite signals for GPS positioning, the second terminal cannot directly obtain assistance from a base station or an Internet server, so that the time for searching the satellite signals to complete positioning is long (usually more than 30 seconds) when the second terminal works alone, and the user experience is poor; particularly, when the second terminal moves to a completely new geographic range, the time required for the GPS unit configured on the second terminal to search satellite signals to complete positioning is longer;

through the communication process provided by the embodiment of the application, the second terminal of the type can establish a communication connection with the first terminal through a short-distance wireless communication function, and then after the first terminal obtains satellite data corresponding to N partitions within a set time range through the communication process between the first terminal and the server, the satellite data can be indirectly obtained through the communication connection established between the first terminal, so that when the first terminal is separated from the first device to work alone, the obtained satellite data can be used for purposefully searching satellite signals, the rapid positioning is realized, and the user experience is improved.

For example, based on the above description related to fig. 1 and fig. 2, in some practical scenarios, the first terminal may specifically be a mobile phone, a tablet computer, a notebook, and the like, and the second terminal may specifically be a smart watch, a smart bracelet, smart glasses, and the like.

Fig. 5 is a schematic diagram illustrating that a bluetooth connection is established between a first terminal and a second terminal in a positioning method according to an embodiment of the present application.

As shown in fig. 5, the first terminal 501 may establish a bluetooth connection with the second terminal 502 configured with a bluetooth function module through the bluetooth function module configured thereon, so that after the first terminal 501 acquires satellite data corresponding to N partitions within a set time range through the process shown in fig. 3, the satellite data may be transmitted to the second terminal 502 through the bluetooth connection, so that the second terminal 502 may search for satellite signals through the GPS unit configured thereon within the set time range.

Specifically, in some scenarios in which the positioning solution provided by the above embodiment of the present Application is implemented by software, the server-side function in the above communication process may be configured as an Application (App) service program configured on a server, and may provide a first type of Application program (or may be denoted as a master App) that can be configured on a first terminal of a type such as a mobile phone, a tablet computer, or the like, and a second type of Application program (or may be denoted as a slave App) that can be configured on a second terminal of a type such as a bluetooth bracelet, a bluetooth watch, or the like;

furthermore, the first terminal can provide satellite data corresponding to the N partitions within a set time range for the first terminal through an App service program on the main App trigger server; the second terminal can trigger the main App of the first terminal to transmit the acquired satellite data corresponding to the N partitions in the set time range through the auxiliary App.

In consideration of the fact that the satellite data may have a large data volume, when software is implemented, corresponding storage spaces may be configured for the App service program, the master App, and the slave App, and specifically, the storage space may be one hundred to two hundred megabytes, for example.

Specifically, for example, fig. 6 shows a communication flow diagram of a positioning method provided in the embodiment of the present application in practical application. As shown in fig. 6, the App service program is configured on the server, the master App is configured on the mobile phone (corresponding to the first terminal), the slave App is configured on the watch (corresponding to the second terminal), and the communication flow is as follows:

step 600: the map is divided into a plurality of partitions (corresponding to the M partitions) in advance according to a predetermined rule.

Alternatively, the map may be downloaded and stored in advance on the server, the cell phone, and the watch.

Specifically, the identification information of each partition obtained by dividing the map can be configured to an App service program on the server, a master App on the mobile phone, and a slave App on the watch.

Step 601: a user starts a main App on a mobile phone;

specifically, after the main App is started, a UI menu may be provided to the user, so as to receive a user instruction for instructing a target time range (corresponding to the above-described set time range) and a target area (corresponding to the above-described N partitions) input by the user.

Step 602: the main App on the mobile phone generates a request message for requesting satellite data corresponding to a target area within a target time range according to the user instruction, and sends the request message to a server;

step 603: after receiving the request message, the App service program on the server analyzes the request message and determines a target time range and a target area corresponding to satellite data required by the mobile phone;

step 604: the App service program on the server starts calculation of satellite data corresponding to the target area within the determined target time range; specifically, the calculation can be performed by acquiring historical satellite data;

step 605: after the App service program on the server obtains the calculation result, a response message carrying the calculation result is generated and fed back to the mobile phone;

step 606: after receiving the response message, the mobile phone analyzes the response message, so that satellite data corresponding to a target area in a target time range is obtained and stored; it can be seen that, through the above steps, the mobile phone can use the acquired satellite data to search satellite signals within the target time range to complete positioning;

step 607: the watch is sensed by a Bluetooth module in the mobile phone close enough to the watch through the Bluetooth module provided by the watch; the mobile phone identifies the watch as a terminal which is authenticated and can communicate with the watch;

step 608: the mobile phone sends satellite data corresponding to a target area in a target time range stored by the mobile phone to the watch through Bluetooth connection established between the mobile phone and the watch;

step 609: the watch stores the received satellite data corresponding to the target area within the target time range, so that the satellite signals can be searched by using the stored satellite data within the target time range to complete positioning, and the defects that the conventional wearable terminal such as a watch needs to poll and search the satellite, the time consumption is long, the positioning is delayed, the user experience is poor and the like are overcome.

In summary, in the positioning scheme provided in the foregoing embodiment of the present application, the map is divided into a plurality of partitions according to the set rule, so that when satellite data corresponding to one or more partitions in a set time range in the future needs to be acquired, the first terminal may send a request message carrying indication information of the set time range and the one or more partitions to the server, and receive a response message returned by the server and carrying satellite data corresponding to the one or more partitions in the set time range, so as to achieve the purpose of quickly acquiring satellite data corresponding to a target area in a target time period;

it can be seen that, because the positioning scheme provided by the above embodiment of the present application divides the map into a plurality of partitions (for example, into administrative areas), and the like, since each partition has a certain longitude and latitude span instead of a specific location (a certain longitude and latitude), the calculation complexity can be reduced and the search time can be shortened when satellite data is estimated;

further, in the positioning scheme provided in the foregoing embodiment of the present application, the server may calculate satellite data corresponding to a target area within a future target period (for example, a day or a longer period of time) based on historical satellite data, and the first terminal may obtain the satellite data corresponding to the target area within the future target period, so that when the target period arrives, if the first terminal is in the target area and needs to search for satellite signals for positioning, the first terminal can quickly acquire satellite signals of satellites located above the target area according to the satellite data corresponding to the target area within the target time range obtained in advance, thereby avoiding a defect of long time required for acquiring satellite signals due to current satellite polling, improving positioning efficiency, and improving user experience, for example, theoretically, if only 4 to 5 PRNs are searched by the positioning scheme provided in the present application, the time required for searching 32 PRNs is greatly reduced compared with the traditional scheme;

in addition, the positioning scheme provided by the embodiment of the application can be specifically realized as an APP scheme, so that the APP scheme can be used by different terminals in the same partition, and can also be used by terminals in different partitions, the used terminals are not limited, the use time is not limited, and the terminal can be quickly positioned after being offline.

Based on the same inventive concept, the application also provides a positioning method.

As shown in fig. 7, the process includes the following steps:

step 702: the server calculates satellite data corresponding to the N partitions within the set time range according to historical satellite data; the satellite data corresponding to one partition comprises satellite data of each satellite passing through the space above the partition within the set time range;

step 703: and the server sends a response message to the first terminal, wherein the response message carries satellite data corresponding to the N partitions within the set time range.
