顾及观测质量的多系统融合PPP三维凸包选星算法
|
摘要
从卫星空间构型出发,构建多系统融合PPP的三维凸包选星算法;为进一步改善多系统融合PPP的定位性能,提出顾及观测质量的三维凸包选星思路;最后结合实测数据验证并分析各自的选星效果和定位性能。
Based on the geometrical layout of satellite constellation, a three-dimensional convex hull satellites selection algorithm for multi-GNSS precise point positioning is constructed. In order to further improve the positioning performance of multi-GNSS PPP, we propose the idea of three-dimensional convex hull satellites selection algorithm considering the quality of observations. Finally, the selection effect and positioning performance of the proposed algorithms are verified and analyzed by employing the measured data.
