A Study of the Kalman Filter Algorithm for TS/GPS/Galileo Combined System

Liu Jianye

Abstract

The Kalman modal of the three-satellites(TS) system was presented,then the extended Kalman filter algorithm for TS/GPS/Galileo system was studied and the structure of the Kalman filter considering the characteristics of the combined system is given.The results show that the model of the Kalman filter is feasible,and under the same error condition,it is more accuracy and robust than the Least square method.
