摘要: 对我国范围内飞机非精密进场及终端航行时全球定位导航系统(GPS)接收机自备完善性监测(RAIM)的可用性进行了研究,分析了气压高度表辅助和故障偏置大小对GPSRAIM可用性的影响。结果表明:气压高度表与GPS组合是提高RAIM可用性的有效措施;过大或过小的偏置误差将产生较小的漏警概率,而中等大小的故障偏置则产生较大的漏警概率

Abstract: A research is presented into the GPS RAIM(receiver autonomous integrity monitoring) availability of the phases of nonprecision approach and terminal navigation over China. The influences of barometric altimeter aiding and bias errors on GPS RAIM availability are analyzed. The simulation results show that the barometric altimeter GPS integration system is an effective measure for improving the GPS RAIM availability, and the large range or small range bias errors will cause small missed detection probabilities, while the middle range bias errors will cause large missed dectection probabilities.

Key words: barometric pressurealtimeters, failure parityvectors
