利用DUFCOM和DC算法的GPS单历元双差整周模糊度快速确定算法

A Fast Fixed Algorithm of GPS Single Epoch Ambiguity Resolution Based on DUFCOM and DC Algorithms

  • 摘要: 为解决DUFCOM方法单历元解算GPS双差整周模糊度因观测卫星数多导致解算效率低而影响GPS高频数据实时动态解算这一问题,同时考虑到DC算法解算效率高的优点,对观测卫星进行筛选分级处理,提出了一种快速确定算法。算例表明,该算法可避免在应用DUFCOM方法中二级卫星对一级卫星双差整周模糊度解算效率的影响,使得GPS单历元确定双差整周模糊度的效率显著提高,达到了GPS高频数据实时动态解算的目的。

     

    Abstract: In order to solve the problem of low efficiency in high frequency GPS real time data processing when the number of observed satellites exceeds 6-8 while using the DUFCOM method,combining DC algorithm with the advantage of extremely high efficiency,a fast fixed algorithm of GPS single epoch ambiguity resolution by screening and classifying processing for the observed satellites is proposed.The results from the example show that the fast fixed algorithm could avoid the influence of resolution efficiency of double-difference integer ambiguity for the second-level satellites acting on first-level satellites,which improve the efficiency for ambiguity resolution greatly,and achieve the aim to high frequency GPS real time kinematic data processing.
