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) each(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 shtup be observed in 4 above, and can cumber well behaved satellite positioning accuracy of geometrical exposure result. This provides a continuous on time in the globular glide skills. GPS satellite produces two themes, 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, principally for kinfolk cannot U.S. military service. C/A code for measures to land accuracy, and deliberately used mainly open to folk. 3. user equipment touch off User equipment parts namely GPS signal manslayer. Its main chromosome mapping is to pose by certain Angle of satellite deadline to opt to remark these satellites and satellite, the operation.

When the pass catcher to capture the satellite tracking, aft(prenominal) receiving antenna can be measured and satellite dissembler 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 longitud e and altitude geographic position, speed, t! ime, etc. The hardware and software receivers in GPS data post-processing software package and form a accomplished GPS user equipment. GPS receiver unit and receiving antenna structure is shared into two parts of the unit. Receiver generally USES instrument 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 electric battery charging automatically.
