BDS系统下RAIM算法可用性及结果分析

摘要

The availability of RAIM algorithm, the principle of fault detection and fault recovery are introduced in this paper. According to the requirements of BDS positioning accuracy, the availability of RAIM algorithm under BDS were obtained by simulation calculation and influences of DOP value on RAIM and ANP availability are analyzed.%本文介绍了接收机自主完好性监测(RAIM)算法的可用性、故障检测及故障排除的原理及方法流程，结合BDS系统下定位精度的需求，通过仿真计算，得到了BDS系统下RAIM算法的可用性结果，并分析了DOP值对RAIM算法可用性及实际导航性能（ANP）的影响。
