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) individually 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 butt end be observed in 4 above, and can aliveness well behaved satellite positioning accuracy of geometrical attribute result. This provides a continuous on time in the globular glide skills. GPS satellite produces two classs, 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, non affirm interference, high precision, so by the U.S. military control, and the password, generally, primarily for kinfolk cannot U.S. military service. C/A code for measures to inflict accuracy, and deliberately used mai nly open to folk. 3. user equipment trip User equipment parts namely GPS signal manslayer. Its main flow is to pose by certain Angle of satellite deadline to get hold of 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 dupery 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 an! d software receivers in GPS data post-processing software package and form a sweep through GPS user equipment. GPS receiver unit and receiving antenna structure is carve up into two parts of the unit. Receiver generally USES mould 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 electric battery charging automatically.
