摘要
描述了通常基于单故障假设相应的HPL 或VPL 的计算模型,针对WAAS用户在应用RAIM时需要顾及多故障的情况,提出了基于漏检概率的可用性分析方法,并通过模拟计算得到一些结论。
This paper introduces the model of calculating HPL and VPL based on the hypothesis of single failure. The RAIM availability analysis method based on the probability of missed detection is propsed, concerning multiple failures of WAAS users. Some results are obtained by simulation.
