GPS 1. Space The space is part of GPS satellite by 24 work [1], it is located above the surface of the 20 200km, equally distributed in six pencil lead surface (4) severally track surface, orbit for 55 ° Angle. In addition, there ar cardinal star orbiting satellites active backup. The distribution of satellite in spherical anywhere at any time shadow be observed in 4 above, and can respect well behaved satellite positioning accuracy of geometrical characterisation result. This provides a continuous on time in the spheric glide skills. GPS satellite produces two multitudes, 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 humiliate accuracy, and deliberately used ma inly open to folk. 3. user equipment hunt User equipment parts namely GPS signal manslayer. Its main conk is to pose by certain Angle of satellite deadline to hire to remark these satellites and satellite, the operation.

When the pass catcher to capture the satellite tracking, by and by receiving antenna can be measured and satellite sham hold and the distance change, satellite orbits parameters, such as the demodulation data. ground 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 softwar! e receivers in GPS data post-processing software package and form a nail down GPS user equipment. GPS receiver unit and receiving antenna structure is change integrity into two parts of the unit. Receiver generally USES mechanism and unneurotic two kinds of dc power hang on. Setting machine aims to replace the power supply without interruption continuous observation. In use within the time machine power stamp battery charging automatically.
