In addition, GPS is the abbreviation of English Global Positioning System (GPS).GPS originates in a project of US military in 1958, within 1964, comes into operation.20 century 70s, land, sea, and air of U.S. joint research and developments Global Positioning System of new generation.Fundamental purpose is for large field, land, sea and air three provides real-time, round-the-clock and global navigation Service, and for some military purposes such as information gathering, Nuclear detonation monitoring and emergency communications, through the research experiment in more than 20 years, cost 30,000,000,000 dollars, by 1994, Global coverage rate up to 98% 24 gps satellite constellations oneself laid.
GPS navigation system is based on 24 positioning satellite in the whole world, provides a kind of radio-navigation positioning system of the information such as three-dimensional position, three-dimensional velocity to all parts of the world round-the-clockly.He is made up of three parts, and one is ground control segment, is made up of master station, ground-plane antenna, monitoring station and communication backup system.Two is space segments, is made up of 24 satellites, is distributed in 6 orbit planes.Three is user's set parts, is made up of GPS and satellite antenna.Civilian positioning precision can reach in 10 meters.
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.Reach this purpose, 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): 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.He 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.
Adopt refuelling station of the present invention oiling vehicle information promulgating platform, for existing fuel station information distribution platform lack refuelling station refuel efficiency relevant information and the technical matters of more effective reference data cannot be provided for driver, adopt the automobile quantity that the high image recognition technology of precision provides the queuing of each refuelling station to refuel, what adopt infrared detection technology to determine each refuelling station goes out vehicle speed, by to the automobile quantity of refuelling station and the reasonable management going out vehicle speed, in conjunction with GPS location technology and wireless communication technology, for its selection refuelling station of relevant information confession of several refuelling stations that driver provides congestion level near current location minimum, to shorten refueling time, thus effectively shunting is realized to the wagon flow in each refuelling station in same city.
