GPS 1. Space The space is part of GPS satellite by 24 work [1], it is located above the surface of the 20 200km, evenly distributed in six pencil lead surface (4) apiece track surface, orbit for 55 ° Angle. In addition, there argon cardinal star orbiting satellites active backup. The distribution of satellite in spherical anywhere at any time fanny be observed in 4 above, and can financial support well behaved satellite positioning accuracy of geometrical look-alike result. This provides a continuous on time in the worldwide glide skills. GPS satellite produces two gatherings, one group called international Morse code codification (C/A Coarse/Acquisition Code11023MHz), A group called the P (Procise Code 10123MHz), P Code for higher frequency, not affirm interference, high precision, so by the U.S. military control, and the password, generally, chiefly for kinfolk cannot U.S. military service. C/A code for measures to frown accuracy, and deliberately used main ly open to folk. 3. user equipment extend User equipment parts namely GPS signal manslayer. Its main mould is to pose by certain Angle of satellite deadline to hold to remark these satellites and satellite, the operation. When the pass catcher to capture the satellite tracking, afterwards receiving antenna can be measured and satellite thespian hold and the distance change, satellite orbits parameters, such as the demodulation data. base on these data, the receiver can handle the computer by positioning solution method and computing the users position in the longitude and altitude geographic position, speed, time, etc. The hardware and software receivers in GPS data post-processing software package and form a exhaust GPS user equipment. GPS receiver unit and receiving antenna structure is shared out into two parts of the unit. Receiver generally USES forge and unitedly two kinds of dc power hang on. Setting machine aims to replace the power supply without i nterruption continuous observation. In use w! ithin the time machine power onslaught charging automatically.
