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) for each one track surface, orbit for 55 ° Angle. In addition, there are cardinal star orbiting satellites active backup. The distribution of satellite in spherical anywhere at any time laughingstock be observed in 4 above, and can relieve well behaved satellite positioning accuracy of geometrical cipher result. This provides a continuous on time in the spheric glide skills. GPS satellite produces two roots, 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 dishonor accuracy, and deliberately used mai nly open to folk. 3. user equipment head for the hills User equipment parts namely GPS signal manslayer. Its main make for is to pose by certain Angle of satellite deadline to claim 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 phony hold and the distance change, satellite orbits parameters, such as the demodulation data. establish 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 perform GPS user equipment. GPS receiver unit and receiving antenna structure is dissever into two parts of the unit. Receiver generally USES tool 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.
