摘要
北斗导航定位系统是我国自主研制的全球导航定位系统,其接收机的自主完好性是决定可靠性的关键因素之一。文章推导了RAIM(Receiver Autonomous Integrity Monitoring)算法的观测模型,并在此基础上推导了基于最小二乘法的RAIM算法、故障检测和故障识别算法。仿真表明,该算法可以检测出故障并识别故障卫星。
Beidou navigation position system is one global navigation position system researched autonomously by China,the autonomous integrity of the receiver is one of the critical factors which decide the receiver＇s reliability. Thus, in this paper, the observation model of the RAIM（Receiver Autonomous Integrity Monitoring） algorithm was deduced, and then the RAIM algorithm was deduced based on the least square algorithm, fault detection algorithm and the fault identification algorithm. The simulation results showed that this algorithm could detect and identify the satellite＇s failure.
