摘要
RAIM是指用户接收机利用多余观测量为定位解自主地提供完善性监测,其基本功能包括故障检测(FD)及故障排除(FE)两个部分。文中对基于奇偶矢量法的GPS接收机自主完善性监测(RAIM)算法进行分析与研究,并以具体数据为例,对该算法进行验证分析。
RAIM can provide integrated autonomous monitoring with redundant observation of user＇s receivers for positioning solution,and its basic functions include fault detection and fault exclusion.The paper discusses the influence of satellite＇s geometrical distribution,presents the parity vector model,introduces the principle of fault detection and exclusion using parity vector by the practical data and validates the RAIM algorithm of parity vector in the end.
