CALCULATE AND APPLICATION OF THE GPS SATELLITE CLOCK OFFSET
-
摘要: 分析了 GPS卫星钟差的变化特性,探讨了利用 GPS地面跟踪站的观测数据估算GPS卫星钟差的可行性.建立了相应的算法和软件系统,并把由地面跟踪站的实测数据估算的卫星钟差用于星载 GPS定轨计算,得到优于1m的定轨精度.Abstract: The characteristics of GPS satellite clock is analysed, and a method to calculate the satellite clock offset is given based on ground GPS station in this paper. With developed algorithm and software, one meter accuracy for low orbit satellite determination is achieved from data of ground tracking station.
