| 摘 要： | 接收机自主完好性监测（RAIM）是卫星导航系统完好性监测的方法之一。一定时空条件下的RAIM可用性，可以通过RAIM空洞直观的反映出来，可以为飞行提供预警；利用不同期GPS、GLONASS实际星座，仿真分析了单星座以及GPS／GLONASS组合星座RAIM可用性，绘制了RAIM空洞图，具有一定的参考价值。

| Abstract: | Receiver Autonomous Integrity Monitoring is one of methods to monitor the performance of navigation system.The RAIM availability algorithm can justify the reliable of RAIM results.The RAIM holes can reflect the RAIM availability directly under a certain space-time scale,and provide warning information of flight imperfect performance.This paper utilizes the actual GPS and GLONASS broadcast ephemeris to simulate the RAIM availability and draw RAIM holes of standalone GPS and integrated GPS/GLONASS.The simulat... |
