摘要
GPS RAIM预测系统提前计算GPS卫星的RAIM可用性,可以为民航机场服务。在该系统的研制过程中,对几种RAIM可用性计算方法进行了研究,最终确定使用HPL方法,该方法原理清晰,计算量小,计算结果准确,易于工程应用。
The GPS RAIM prediction system can calculate the RAIM availability of GPS satellites ahead, and can serve in the civil aviation airport. In the course of the system development, several RAIM availability calculation methods are investigated, and finally HPL method is determined to use. This method has the characters of distinct principle, low amount of calculation, exact computing result, and easy to engineering application.
