Wherein, external GNSS antenna 10 is linked together by antenna jack 201 pluggablely with mobile terminal 20.
Specifically, plug 101 is inserted antenna jack 201 by external GNSS diversity antenna 10, and antenna jack 201 is with mobile Mainboard (not shown) in terminal 20 is connected, when external GNSS diversity antenna 10 inserts antenna jack 201, and external GNSS The first GNSS signal received by diversity antenna 10 feeds back in mainboard.
Mobile terminal can include GNSS main collection antenna 202 and processing module 203, wherein:
GNSS main collection antenna 202 is for generating the second GNSS signal.
Processing module 203 is for positioning according to the first GNSS signal and the second GNSS signal.
It is appreciated that GNSS system refers to all of satellite navigation system, including the whole world, region and enhancing, as The GPS of the U.S., Muscovite GLONASS (GLONASS GPS), Galileo (the Galileo whole world in Europe Satellite navigation system), big-dipper satellite (BeiDou) navigation system of China, and relevant enhancing system, such as the WAAS of the U.S. (Multi-functional transporting satellite increases the MSAS of (WAAS), the EGNOS (Europe geostationary Navigation Overlay System) in Europe and Japan Strong system) etc., it is also contemplated by building and other satellite navigation systems to be built.Therefore, according to the difference of GNSS system, defend Diversity antenna used in star navigation system also can be different.
In one embodiment of the invention, external GNSS diversity antenna 10 can include but not limited to Big Dipper diversity sky Line, Galileo diversity antenna and GLONASS diversity antenna.
Wherein it is desired to be understood by, the type of external GNSS diversity antenna 10 can according to the design requirement of mobile terminal and/ Or mobile terminal the area that used or region set.
The standard supported due to external GNSS diversity antenna 10 is not quite similar, and such as, external GNSS diversity antenna 10 can To support BEIDOU standard, GPS standard, GLONASS standard and GALIEO standard.
It addition, in actual application, according to application scenarios demand, external GNSS diversity antenna 10 can also be supported several Plant the combination of standard.
In one embodiment of the invention, so that processing module 203 can pass through the first GNSS signal and second GNSS signal is accurately positioned, and processing module 203 is additionally operable to the standard of the external GNSS diversity antenna 10 that detection is inserted, and root Standard according to the external GNSS diversity antenna 10 inserted adjusts the resonance point of GNSS main collection antenna 202, so that GNSS main collection antenna 202 is identical with the standard of external GNSS diversity antenna 10.Thus, by by main for GNSS collection antenna 202 and external GNSS diversity sky The standard of line 10 keeps consistent, improves high-gain and the location efficiency of antenna, improves the GNSS antenna system of mobile terminal Availability and feasibility.
The global navigation satellite system GNSS antenna system of the mobile terminal of the embodiment of the present invention, is provided with in mobile terminal Antenna jack, when needs use GNSS main collection antenna, can pass through described antenna jack with described by external GNSS diversity antenna Mobile terminal links together pluggablely, thus, facilitates user and plugs GNSS diversity antenna according to demand, by GNSS master Diversity antenna receives signal, it is possible to reduce the deterioration of the docking collection of letters number such as spatial fading, and then makes mobile terminal pass through GNSS Signal received by main collection antenna and GNSS diversity antenna carries out fixing location.
Fig. 2 is the global navigation satellite system GNSS antenna system of the mobile terminal according to another embodiment of the present invention Structural representation.
It is described as in figure 2 it is shown, this antenna system is positioned at as a example by the right side of mobile terminal 20 by antenna jack 201.
Generally, the GNSS main collection antenna 202 in mobile terminal 20 can individually be pre-designed, it is also possible to whole with mobile Other existing antenna duplexers in end 20.
In one embodiment of the invention, the main antenna 202 that integrates of GNSS is as GPS main collection antenna, i.e. GNSS main collection antenna 202 with GPS main collection antenna duplexer, say, that GPS main collection antenna can also use, by this GPS as GNSS main collection antenna Main collection antenna can also receive GNSS signal.
In order to reduce the quantity of antenna in mobile terminal, and reduce the interference between antenna, at another of the present invention In embodiment, GNSS main collection antenna 202 can share with radio antenna.
Such as, GNSS main collection antenna 202 can be with WiFi antenna duplexer.
And for example, GNSS main collection antenna 202 can share with Bluetooth antenna.
Wherein it is desired to be understood by, above-mentioned WiFi antenna and Bluetooth antenna are only the examples of radio antenna, this enforcement The Bluetooth antenna of example is not restricted to this.
When GNSS main collection antenna 202 shares with radio antenna, in order to the signal being received can be distinguished it is Second GNSS signal, or wireless communication signals, in one embodiment of the invention, as in figure 2 it is shown, this mobile terminal 20 is also Can include frequency divider 204, this frequency divider 204 collection main with GNSS antenna 202 is connected, for by the second GNSS signal and channel radio Letter signal separates.
In monitoring frequency divider 204, the signal of output is the second GNSS signal, and processing module 203 is believed based on a GNSS Number and the second GNSS signal accurately mobile terminal 20 is positioned.
In one embodiment of the invention, in order to improve the receiving ability of signal, in order to reduce between main diversity antenna Interfere, it is also possible to main for GNSS collection antenna 202 and external GNSS diversity antenna 10 are set to different towards, i.e. GNSS Main collection antenna 202 and external GNSS diversity antenna 10 towards difference.Thus, it is possible to avoid antenna towards unification can cause work as During rotation of mobile terminal direction, GNSS antenna is easily blocked by entirety, and the positioning function of GNSS so can be caused significantly to be cut Weak.
The global navigation satellite system GNSS antenna system of the mobile terminal of the embodiment of the present invention, is provided with in mobile terminal Antenna jack, when needs use GNSS main collection antenna, can pass through described antenna jack with described by external GNSS diversity antenna Mobile terminal links together pluggablely, and when monitoring GNSS main collection antenna and sharing with radio antenna, by dividing Frequently device is recognized accurately received signal is the second GNSS signal or wireless communication signals, and received signal is During the second GNSS signal, mobile terminal is accurately positioned by processing module based on the first GNSS signal and the second GNSS signal, Thus, facilitate user and plug GNSS diversity antenna according to demand, receive signal by the main diversity antenna of GNSS, it is possible to reduce be empty Between the deterioration collected mail number of the docking such as decline, and then make mobile terminal pass through GNSS main collection antenna and GNSS diversity antenna is received To signal carry out fixing location.
In order to realize above-described embodiment, the present invention also proposes a kind of mobile terminal.
Mobile terminal according to an embodiment of the invention, including GNSS days of the mobile terminal of any embodiment of the present invention Wire system.
The mobile terminal of the embodiment of the present invention, is provided with antenna jack in mobile terminal, use GNSS main collection sky at needs During line, external GNSS diversity antenna can be passed through described antenna jack and link together pluggablely with described mobile terminal, by This, facilitate user and plug GNSS diversity antenna according to demand, receives signal by the main diversity antenna of GNSS, it is possible to reduce space The deterioration of the docking collections of letters number such as decline, and then mobile terminal is passed through received by GNSS main collection antenna and GNSS diversity antenna Signal carry out fixing location.
