摘　　要：为了满足保障生命安全以及航空航天高精度、高可靠导航的要求,GNSS接收机不但要提供精确的导航服务而且也要提供完好性服务。为此,用于故障卫星检测和隔离的不同RAIM算法已被国内外学者广泛研究。文中首先介绍了RAIM算法的原理,然后对国内外用于单颗和多颗卫星故障检测与隔离的RAIM算法研究进展进行系统的综述和深入的分析,并对多星座GNSS接收机完好性监测算法进行了深入细致的论述。另外对GPS最新的用户接口文件在定位精度以及可靠性方面的改善进行了介绍,最后总结给出了RAIM算法的主要研究方向。In order to meet the demand of high precision and reliability in safety-critical applications and aeronautical and astronautical navigation systems, GNSS should support both high precision navigation service and integrity service. Therefore, the RAIM algorithm for failed satellites detection and isolation has become the focus for research both at home and abroad. This paper, first presents the principle of RAIM; then gives,systemic description and in-depth analysis on RAIM algorithm for detecting or isolating single or multiple satellite failures, It also discusses the integrity monitoring scheme supported by multi-constellation satellite navigation positioning systems and the performance of the GNSS RAIN algorithm. In addition, new features of the GPS user interface control document are provided. Finally, it forecasts the potential trend for RAIM research.
