摘要
介绍最大水平精度因子法和近似径向误差保护法两种RAIM可用性分析方法。采用GPS和GLONASS广播星历,通过数据仿真,用不同方法计算多种环境下的RAIM可用性概率。通过比较,说明在多故障、多星座环境下,BIT是更合适的可用性分析方法。
Two RAIM availability analysis methods are introduced.Using the actual GPS and GLONASS broadcast ephemeris and simulated ground grids,results of RAIM availability of different conditions are computed.Through comparison,the BIT method is considered to be the suitable one on the multi-fault and multi-constellation condition.
