Abstract The estimation of relative satellite clock is discussed and three observation network layout schemes are designed.By using data from different networks, different satellite clock error results can be obtained and used for PPP calculation, and then their impacts on the positioning accuracy are analyzed.The results show that the satellite clock estimation does not depend on the location of GPS stations, and the estimation of the satellite clock from a small region is still valuable.
Key words ：
