Description
Technical field
The present invention relates to a kind of positioning indicating mobile phone, especially a kind of GPS mobile phone that has destination prompting function.
Background technology
The vehicles as bus, subway etc., are present social people's work, the requisite trip mode of living.But the passenger may be very strange to road, do not know its position, and a lot of vehicles have brought very big trouble because of the inaccurate passenger's of the giving riding public transportation means of not calling out the stops or call out the stops.And, the timely vehicles function of calling out the stops, the passenger must notice constantly that also calling out the stops of the vehicles just come great inconvenience.
For example: can find a lot of people all in sleep when we take public transport, may be because tired out or boring or the like reason. but also have the people can because sleep do when missing the stop.
The present invention also uses following prior art:
GPS is the abbreviation of English Global Positioning System (global positioning system), and its Chinese abbreviates " ball position system " as.GPS is the of new generation Aerospace Satellite navigation positioning system of the seventies in 20th century by U.S. land, sea, and air joint research and development.Its main purpose is for three big fields, land, sea, air provide real-time, round-the-clock and global navigation Service, and is used for some military purposes such as information acquisition, nuclear blast monitoring and emergency communication, is the important composition that the U.S. dominates global strategy exclusively.Through the research experiment in surplus 20 years, expensive 30,000,000,000 dollars, in March, 1994, oneself laid and finishes global coverage rate up to 24 gps satellite constellations of 98%.At mechanical field GPS another implication is arranged then: product geometric techniques standard (Geometrical Product Specifications)-abbreviation GPS.
The basic principle of GPS navigation system is to measure the satellite of known location to the distance between the receiver user, and the data of comprehensive multi-satellite are just known the particular location of receiver then.Reach this purpose, the position of satellite can be found in satellite ephemeris according to the time that spaceborne clock write down.The user then propagates into the time that the user experiences by the record satellite-signal to the distance of satellite, again it be multiply by the light velocity and obtain (because the ionospheric interference of atmosphere, this distance is not the actual distance between user and the satellite, but pseudorange (PR): when the gps satellite operate as normal, pseudo noise code (abbreviation pseudo-code) the emission navigation message that can constantly form with 1 and 0 binary element.The pseudo-code one that gps system uses has two kinds, is respectively civilian C/A sign indicating number and military P (Y) sign indicating number.C/A code frequency 1.023MHz, one millisecond of repetition period, intersymbol is equivalent to 300m apart from 1 microsecond; P code frequency 10.23MHz, 266.4 days repetition periods, intersymbol is equivalent to 30m apart from 0.1 microsecond.And the Y sign indicating number is to form on the basis of P sign indicating number, and security performance is better.Navigation message comprises information such as satellite ephemeris, working condition, clock correction, ionospheric delay correction, atmospheric refraction correction.It is that rectification comes out from satellite-signal, is modulated at 50b/s and launches on the carrier frequency.Comprise 5 every frame length 6s of subframe in each prime frame of navigation message.Each 10 character code of first three frame; Per 30 seconds repeat once, per hour upgrade once.Back two frames are 15000b altogether.Content in the navigation message mainly contains telemetry code, hand over word, the 1st, 2,3 data blocks, and wherein most important then is almanac data.When the user receives navigation message, extract satellite time and its clock with oneself is done the distance that contrast just can be learnt satellite and user, present position when utilizing satellite almanac data in the navigation message to extrapolate the satellites transmits text again, the information such as position and speed of user in the WGS-84 earth coordinates just can be learnt.
As seen the effect of GPS navigation system satellite portion is exactly constantly to launch navigation message.Yet, because clock and satellite carried clock that user's receiver uses can not be always synchronous, so except user's three-dimensional coordinate x, y, z, also will introduce a Δ t and be time difference between satellite and the receiver, with 4 equations these 4 unknown numbers be separated out then as unknown number.If, want to receive the signal of 4 satellites at least so wonder the residing position of receiver.
The GPS receiver can receive the accurate temporal information to nanosecond that can be used for time service; Be used to forecast the forecast ephemeris of satellite general location of living in coming few months; The broadcast ephemeris of required co-ordinates of satellite when being used for compute location, precision are several meters to tens meters (each satellite difference changes at any time); And gps system information, as satellite situation etc.
The GPS receiver just can obtain the distance of satellite to receiver to the measurement of sign indicating number, owing to contain the error and the atmospheric propagation error of receiver satellite clock, so be called pseudorange.The pseudorange that the 0A sign indicating number is recorded is called UA sign indicating number pseudorange, and precision is about about 20 meters, and the pseudorange that the P sign indicating number is recorded is called P sign indicating number pseudorange, and precision is about about 2 meters.
The satellite-signal of GPS receiver to receiving decoded or adopted other technology, after the information on the carrier wave of being modulated at is removed, and just can the reinsertion of carrier.Strict, carrier phase should be called as carrier wave beat frequency phase place, and it is that the satellite signal carrier phase place and the receiver local oscillation that influenced by Doppler frequency shift received produce the poor of signal phase.Generally measure constantly in the epoch that the receiver clock is determined, maintenance is to the tracking of satellite-signal, just can note the changing value of phase place, but the phase place initial value of receiver when beginning to observe and satellite oscillator is ignorant, the phase place integer of initial epoch also is ignorant, be integer ambiguity, can only be as parameter calculation in data processing.The precision of phase observations value is high to millimeter, but prerequisite is to solve integer ambiguity, therefore only could use the phase observations value at relative positioning and when one section continuous measurements is arranged, and also can only adopt the phase observations value and will reach the positioning accuracy that is better than meter level.
By locate mode, the GPS location is divided into single-point location and relative positioning (difference location).Single-point location is exactly a mode of determining receiver location according to the observation data of a receiver, and it can only adopt pseudo range observed quantity, can be used for the summary navigator fix of car and boat etc.Relative positioning (difference location) is a method of determining the relative position between the observation station according to the observation data of two above receivers, it both can adopt pseudo range observed quantity also can adopt the phase observations amount, and geodesic survey or engineering survey all should adopt the phase observations value to carry out relative positioning.
The clock correction, atmospheric propagation delay, the multipath effect equal error that in the GPS observed quantity, have comprised satellite and receiver, when location Calculation, also to be subjected to the influence of satellite broadcasting ephemeris error, most of common error is cancelled or weakens when carrying out relative positioning, therefore positioning accuracy will improve greatly, dual-frequency receiver can be offset the major part of ionospheric error in the atmosphere according to the observed quantity of two frequencies, at the required precision height, when distance is far away between receiver (atmosphere has significant difference), should select dual-frequency receiver for use.
In view of this, this area inventor provides a kind of GPS mobile phone that has destination prompting function at the problems referred to above.
