| 摘 要： | 提出一种适用于多星座情况的接收机自主完好性监测算法——基于完好性指标动态分配的完好性监测算法。该算法比传统算法更能适应多星座情况下不同星座观测量属性的差异，其可用性比传统算法提高2％～3％。在多星座和双频情况下，利用该算法分析完好性监测的性能，结果表明，该算法在LPV-200完好性要求下是适用的。

| Abstract: | This paper presents a new Receiver Autonomous Integrity Monitoring(RAIM) algorithm based on Probability of Hazardously Misleading Information(PHMI) dynamically allocated strategy.This algorithm is feasible to fuse multi-constellation measurements for integrity monitoring.It also dynamically allocates PHMI among all satellites used to get a solution,which improves the availability of traditional RAIM algorithms at 2% to 3%.With the algorithm,it analyzes the integrity monitoring performance of GPS and GPS/Gal... |
