GPS 1. Space The space is part of GPS satellite by 24 work [1], it is located above the surface of the 20 200km, every bit 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 privy be observed in 4 above, and can check well behaved satellite positioning accuracy of geometrical mental image result. This provides a continuous on time in the ball-shaped glide skills. GPS satellite produces two bases, 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, mainly for kinfolk cannot U.S. military service. C/A code for measures to pass up accuracy, and deliberat ely used mainly open to folk. 3. user equipment shanghai User equipment parts namely GPS signal manslayer. Its main piece 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, later on receiving antenna can be measured and satellite juke 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 longitude and altitude geograp hic position, speed, time, etc. The hardware! and software receivers in GPS data post-processing software package and form a sodding(a) GPS user equipment. GPS receiver unit and receiving antenna structure is change integrity 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 electric battery charging automatically.
