摘要:

高级接收机自主完好性监测(ARAIM)是单频RAIM 的扩展。基于对垂直保护限值(VPL)和有效监视门限(EMT)的分析,给出了垂直方向ARAIM 的VPL 实时和预测算法;对LPV-200 进近,从单星座ARAIM的可用性出发,研究了双星座、多故障情况下ARAIM 的可用性;对世界范围内ARAIM 的可用性进行仿真,给出仿真统计,并对中国西部航路区域ARAIM 的可用性进行仿真,结果表明,在双星座双频情况下,可用性设置为99.9%时ARAIM 的算法覆盖率可达100%,完全满足LPV-200 进近对完好性的要求。

Abstract:

Advanced receiver autonomous integrity monitoring (ARAIM) is an extension of single-frequency RAIM. The real-time and predicted algorithm for ARAIM vertical protection level (VPL) is given based on the analysis of VPL and effective monitor threshold (EMT). For LPV-200 approach,the ARAIM availability for single constellation is studied first,then the research of ARAIM availability for the condition of dual-constellation and multi-satellite failures is focused on. The worldwide availability of ARAIM is simulated,as well as the ARAIM availability for the area of the western route of China,and the simulation statistic for worldwide ARAIMavailability is made.The results show that the coverage rate of RAIM 99.9% availability can reach 100% for the condition of dualconstellation and dual-frequency,which fully meets the requirements of integrity for LPV-200 approach.

Key words: advanced receiver autonomous integrity monitoring (ARAIM), GNSS, VPL, EMT, MHSS
