Description
Technical field
The present invention relates to the communications field, in particular to a kind of satellite positioning method, apparatus and system.
Background technology
Location service（Location Based Service, referred to as LBS）Refer to mobile network by specific positioning
Technology obtaining the positional information of mobile terminal, so as to provide a kind of value-added service of Additional Services for terminal use, can be extensive
It is applied to all many-sides such as emergency relief, navigation tracking, transportation dispatching, mobile yellow pages.
In recent years, with the increase of user's request, mobile positioning technique is received more and more attention, particularly 3G, 4G
The increasingly mature development for mobile positioning technique of technology provides support.In the network of 2G or 2.5G, due to being subject to network
The restriction of transmission speed, the global positioning system of high-precision location technique network assistance（Assisted Global
Positioning System, referred to as A-GPS）Application limited to, and 3G, 4G network can provide high-speed radio download
Function, this just provide more wide development space for mobile location service.
A-GPS（Assisted Global Positioning System）That is the global positioning system of network assistance, this
The method of kind needs network and mobile terminal receive GPS information, is that one kind combines network base station information and GPS information pair
The technology positioned by mobile terminal, can be used in 2G and 3G network.The advantage of this technology mainly in its positioning precision,
In open spaces such as outdoors, under normal operation circumstances, its precision can be rated as current positioning precision highest a kind of fixed up to 5～10m
Position technology.On the other hand, the auxiliary information for being transmitted using network can strengthen primary positioning time（Time To First Fix,
Referred to as TTFF）, its time for capturing gps signal first greatly reduces, normally only needs several seconds, and unlike global positioning system
（Global Position System, referred to as GPS）Capture time first may need 2～3 minutes (min).A-GPS is fixed
Position response time is 3～10 seconds（s）Between.
Used as a kind of high-precision mobile positioning technique, A-GPS is obtained jointly by mobile terminal and GPS auxiliary positioning information
The positional information of mobile terminal is taken, so that increasing A-GPS receiver modules in mobile terminal（Or external A-GPS connects
Receipts machine）, while on network plus the equipment such as location server, reference receiver will be built.
The positioning flow of A-GPS is as follows：
（1）Mobile terminal is first by the base station address of itself by network transmission to location server.
（2）Location server transmits the satellite assistance data related to the position according to the Position Approximate of the terminal, for example：
GPS ephemeris etc..
（3）Using these information, the A-GPS modules of terminal can capture satellite quickly, to lift the first lock of gps signal
Fix time（Namely TTFF）Ability, and GPS primary signals are received, after demodulated signal, the pseudorange of computing terminal to satellite, its
In, pseudorange is exactly the distance affected by various GPS errors.
（4）Terminal completes the calculating to exact position according to the GPS pseudoranges and gps satellite auxiliary information that measure.
It should be noted that the satellite assistance data in whole scheme is provided by reference receiver.Reference receiver is real-time
Ground obtains reference data from satellite（For example, clock, ephemeris, constellation, reference position etc. can be used）, position is supplied to by network
Put server.When mobile terminal needs satellite data, location server provides A-GPS supplementary numbers by wireless network to terminal
According to strengthen its TTTF, so as to greatly improve the sensitivity of A-GPS receiver modules.
But, the shortcoming of current AGPS services practical application is：
1st, the problem of reference receiver distribution, due to reference receiver negligible amounts, skewness, can so cause data
Not fine accurate enough, so as to locating speed is slower.
