导航卫星精密钟差估计及精度分析
Precision analysis and precise clock error estimation of navigation satellites
研究了导航卫星精密钟差的估计算法，编程实现了基于非差载波相位的精密卫星钟差的解算，并同IGS若干分析中心提供的精密钟差产品进行了比较。结果表明：采用自编软件解算的精密卫星钟差产品同IGS最终、COD、JPL及MIT的精密卫星钟差产品吻合较好，互差优于0.1 ns，精度与当前IGS最终精密钟差基本相当。
he precise satellites clock error estimation algorithm of navigation satellites is studied in this paper. The computation of precise satellites clock error based on the non-difference phase is realized and the results are compared with the products provided by IGS analysis centers. The results show that: the precise satellites clock products calculated by the software are equal to those provided by IGS Final, COD, JPL and MIT Their bias are less than 0.1ns and the precision is equal to the precision of IGS Final.
