ＲＴＣＡＳＣ－１５９完善性工作小组提出实现ＧＰＳ完善性监测的技术可以分成两类：一类为内部法，如处理接收机内部的冗余信息或来自其它传感器的辅助信息；另一类为外部法，如ＧＩＣ或ＤＧＰＳ。本文将主要讨论内部方法中ＧＰＳ／ＩＮＳ组合系统、ＡＲＰ方法及ＧＰＳ／气压高度表组合在我国ＧＰＳ完善性监测中的应用
The RTCASC-159 Sounding Working Group proposed technologies for GPS sound monitoring that fall into two categories: internal ones, such as handling redundant information inside the receiver or ancillary information from other sensors; and the other for external law, Such as GIC or DGPS. This article will mainly discuss the application of GPS / INS combination system, ARP method and GPS / barometric altimeter combination in the GPS method in our country
