Description
Technical field
The utility model relates to technical field of satellite, particularly relates to a kind of GPS positioning system.
Background technology
Along with the fast development of modern society, people propose more and more higher requirement to location technology.GPS (Global Positioning System, GPS) is more and more subject to people's attention.GPS can provide the functions such as vehicle location, antitheft, anti-misfortune, travel route monitoring and calling commander.
The ultimate principle of GPS navigation system is the distance between the satellite of measuring known location to receiver user, and then the data of comprehensive multi-satellite just can know the particular location of receiver.Particularly, the time that the position of satellite can be recorded according to spaceborne clock finds in satellite ephemeris.User then propagates into by record satellite-signal the time that user experiences to the distance of satellite, being multiplied by the light velocity again obtains (due to the ionospheric interference of atmospheric envelope, this distance is not the actual distance between user and satellite, but pseudorange (PR,): when gps satellite normally works, constantly navigation message can be launched by the pseudo-random code (abbreviation pseudo-code) of 1 and 0 binary element composition.The pseudo-code one that gps system uses has two kinds, is civilian C/A code and military P (Y) code respectively.C/A code frequency 1.023MHz, the repetition period one millisecond, intersymbol, apart from 1 microsecond, is equivalent to 300m; P code frequency 10.23MHz, 266.4 days repetition periods, intersymbol, apart from 0.1 microsecond, is equivalent to 30m.And Y code is formed on the basis of P code, security performance is better.Navigation message comprises the information such as satellite ephemeris, working condition, clock correction, ionospheric delay correction, refraction correction.It is that rectification out, is modulated at 50b/s and carrier frequency launches from satellite-signal.5 every frame length 6s of subframe are comprised in each prime frame of navigation message.Each 10 character codes of first three frame; Every 30 seconds repeat once, and renewal per hour once.Rear two frames are 15000b altogether.Content in navigation message mainly contain telemetry code, hand over word, the 1st, 2,3 data blocks, wherein most important is then almanac data.When user receives navigation message, extract satellite time and the clock of itself and oneself is contrasted the distance just can learning satellite and user, present position when satellite almanac data in recycling navigation message extrapolates satellite launch text, the information such as the position and speed of user in WGS-84 earth coordinates just can be learnt.
But in A-GPS location, often there is user obtains auxiliary data communication from base station when positioning.In addition, after obtaining these auxiliary datas, during carrying out GPS location, standard design does not allow yet cut off corresponding communication.Further, when positioning, all need to carry out C-Plane connection at every turn, from location, all must maintain C-Plane carrying to end.The power consumption that consequently leads to based on communication increases, and also increases the traffic load of the network equipment.
Summary of the invention
For the problems referred to above, the utility model provides a kind of GPS positioning system, is intended to solve in prior art large based on the power consumption of communication, and the technical matters large to the traffic load of the network equipment.
For achieving the above object, the utility model comprises GPS locating terminal and GPS location-server; Described GPS positioning system comprises: storer, processor, non-communicating type steady arm and communication type steady arm; Described storer is connected with described processor; Described processor is connected with described non-communicating type steady arm; Described processor is connected with described communication type steady arm; Described storer is used for the auxiliary data of GPS location; Described processor is effective or invalid according to the storage auxiliary data in described storer; Described non-communicating type steady arm, when processor judges that described storage auxiliary data is effective, carries out GPS location according to described effective storage auxiliary data; Described communication type positioning unit, when processor judges that described storage auxiliary data is invalid, carries out GPS location according to the auxiliary data that the communication between server obtains; Described processor also for, when described non-communicating type steady arm or described communication type steady arm are located successfully, according to this positioning result, described storage auxiliary data is upgraded, and by upgrade after data preserve in memory; Described processor also for, when described non-communicating type steady arm or described communication type steady arm are located unsuccessfully, obtain auxiliary data by the communication between server, upgrade described storage auxiliary data, and the auxiliary data after upgrading is stored in described storer.
Further, described processor also for locate at described GPS middle-end move in fixed area or carry out transregional mobile time, upgrade described storage auxiliary data.
Further, described non-communicating type steady arm is independently located; Described communication type steady arm carries out the GPS location of network assistance type.
Compared with existing GPS positioning system, the utility model provides a kind of GPS positioning system, by arranging non-communicating type steady arm and communication type steady arm in system, and adjust in real time according to the positioning states of two devices, make the positioning precision of GPS higher, the efficiency of location is higher, and locating speed is also more convenient.
