为解决卫星相对钟差估计问题,设计3种观测网布设方案,比较采用不同网型数据计算的卫星钟差结果,并将计算所得的卫星钟差应用于精密单点定位计算,分析其对定位精度的影响.结果显示,卫星钟差的计算模式与跟踪站位置无关,小区域计算的卫星钟差也具有较高的应用价值.

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.
