摘要
影响GPS高精度定位和低轨卫星高精度定轨等的一个重要因素就是卫星钟差,具体分析、比较了采用不同多项式内插来加密GPS精密卫星钟差的方法,并对德国GFZ(Geo Forschungs Zentrum)数据处理中心提供的精密卫星钟差进行处理,通过MATLAB编程计算后,比较了不同加密方法处理的精密卫星钟差的结果,得出了一些有益的结论。
Satellite clock offset is an important factor in influencing GPS high-precision positioning and Low--Earth--Orbiter orbiting, so the author analyzes and compares densification methods of different polynomial interpolation for clock offsets of precise GPS satellites in detail, and processes datum offered by GFZ using the several densification methods and further compares results from the datum processing by programming with MATLAB. Some useful results are presented.
