The Densification GPS Precise Ephemeris and Accuracy Test for based on Algorithm Neville
摘要
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.关键词
