Artillery With Gps / Glonass Positioning System

This paper is based on the Scientific research project of Special Positioning Service which will employ in artillery. The technique request of the ArtiJlery Positioning System is introduced. The paper proposed the scheme of the project in detail, as well as the design of hardware and software. The terminal designed is demonstrated as theory model. Besides, simulation is processed from receiving the raw data to the GPS data procession .The paper finally discussed some methods to improve precision Phase smooth Pseudo-range and Carrier Phase Observation. Using the way of Phase smooth Pseudo-range, the precision can reach several meters and centimeters or even less using Carrier Phase Observation. To capture GPS integer ambiguity is a problem still discussing in the technique of Carrier Phase measurement. A way of improvement for fast GPS ambiguity resolution is presented. The simulation results show precision can be improved in this way.
