Abstract

High dynamic China area positioning system signal simulation testing system are constructed by a space vehicle moving simulation system, CAPS signal simulator, CAPS base station, CAPS mobile station and Simulation control computer. Space vehicle moving simulation system generates static or dynamic position information, then send data to CAPS signal simulator through Ethernet. CAPS simulator produces navigation signal through the space vehicle position information. CAPS base station and mobile station can receive both CAPS satellite signal and CAPS simulator signal. CAPS base station transmits wireless difference data to CAPS mobile station in real time. This system has function of navigating, positioning, timing and speed measurement. The results from experiment show that bias of mean of longitude, latitude and altitude are 0.2632 m, 0.6080 m and 0.2318 m respectively; bias of mean of speed is 0.0764 m/s, variance is 0.2195 when the space vehicle is moving in 300 m/s, but they are 0.2004 m/s and 0.15094 respectively when in 500 m/s.
