Abstract :
In general, GEO satellite is used retransmit the signal in two-way time synchronous system. Keeping synchronous motion with earth, the satellite swing slightly, which have effect on the performance of two-way time synchronization. We can analyze the error caused by satellite movement from two aspects, including time synchronization error between stations, and distance difference from stations to satellite. This document analyzes and calculates the errors of two-way time synchronization cause by the two aspects. In addition, the same work is done when the IGSO satellite is used as retransmission satellite. The effect of satellite movement on two-way time synchronization performance has close relationship with the performance and motion mode of satellite.
