摘要
概述了GPS接收机自主完好性监测(RAIM,Receiver Autonomous Integrity Monitoring)现行的几种算法;针对惯用的最小二乘残差法,提出了一种扩展的最小二乘算法—"全局最小二乘法",用以提高RAIM算法的可靠性;给出了基于该种算法下的RAIM解算模型。同时利用IGS站的实测数据进行计算分析,验证了该算法的可用性。
In this paper,some HAIM algorithms are firstly generalized. Aims to Least Squares Residual Method,the author introduces a new algorithm＂Total Least Squares＂to improve the reliability of RAIM. RAIM solution model based on this algorithm is illustrated. By using raw data from Wuhan IGS station,effectiveness of this algorithm is proved.
