Abstract :
Precise time synchronization is the precondition of precise navigation in radio navigation system, high frequency stability cesium atomic clock is used in this system as frequency reference and GPS time receiver is used. To solve the problem of system synchronize error caused by low quality of GPS time receiver in short time, shift average method and Kalman filter is introduced in this paper. The results of simulation indicate that Kalman filter can decrease the error caused by GPS time receiver jitter effectively.
