Description
Technical field
The utility model relates to technical field of satellite, particularly relates to a kind of GPS positioning system for bus location.
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.
On the other hand, along with the raising of people's living standard, automobile becomes the daily necessities of people gradually.GPS car position system generally comprises following several part: GPS car-mounted terminal, communication link and control center.Wherein GPS car-mounted terminal is generally by external several large company's Development and Production, and technology is fairly perfect, can as a module in use.Communication link has multiple realization scheme, as wireless station, microwave network, trunking communication net and GSM net etc.But the value of the GPS car position system of domestic construction is limited, reason is that existing car position system exists the defect of the little and poor real of capacity, and the reason producing this two large defect is selecting of communication link.
