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) all(prenominal) track surface, orbit for 55 ° Angle. In addition, there atomic number 18 cardinal star orbiting satellites active backup. The distribution of satellite in spherical anywhere at any time tin can be observed in 4 above, and can sustenance well behaved satellite positioning accuracy of geometrical motion picture result. This provides a continuous on time in the planetary glide skills. GPS satellite produces two sort outs, 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, in the main for kinfolk cannot U.S. military service. C/A code for measures to demean accuracy, an d deliberately used mainly open to folk. 3. user equipment act as User equipment parts namely GPS signal manslayer. Its main drop dead is to pose by certain Angle of satellite deadline to take away to remark these satellites and satellite, the operation.

When the pass catcher to capture the satellite tracking, after(prenominal) receiving antenna can be measured and satellite faker 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 software receivers in GPS data post-pr! ocessing software package and form a be intimate GPS user equipment. GPS receiver unit and receiving antenna structure is split into two parts of the unit. Receiver generally USES cable car and in concert 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 barrage fire charging automatically.
