| 摘 要： | 国际地球动力学服务组织(IGS)提供的精密星历的数据间隔是15min,远远不能满足实际数据处理需要。利用纳维尔(Neville)算法编程实现对IGS精密星历的卫星坐标和钟差的加密,并将卫星坐标插值结果与广播星历计算得到的坐标结果进行对比得到有益结论,钟差插值结果与IGS提供30s钟差数据进行比较得到较高精度的结果。

| Abstract: | The data interval of the precise ephemeris provided by IGS is 15 minutes, which is far from the meeting of actual data processing. Using algorithm Neville to implement the densification for the satellite cordinates and clock offsets of the IGS precise ephemeris, and a useful conclusion comes out by the comparison on the results of interpolation and cal- culated cordinates through the broadcast ephemeris. The accuracy of clock offsets interpola- tion is proved well by the comparison with the IGS 30 s＇ clk file. |
