卫星导航系统中的RAIM技术

The Receiver Autonomous Integrity Monitor Technology in the Satellite Navigation System

】全球定位系统（ＧＰＳ）已经达到初始运行能力，其完好性还不能满足全部飞行阶段的要求。接收机自主完好性监控（ＲＡＩＭ）为ＧＰＳ的航空用户提供了完好性监控手段。文中集中讨论了实现ＲＡＩＭ的几种检测和判定方法。

Although the global position system(GPS) has reached an initial operational level the integrity of the current systems can not meet the need of flights yet. The receiver autonomous integrity monitor(RAIM)provides a means of integrity monitor for the GPS aviation users. The paper discusses several methods of RAIM and evaluates the relevant technology and potentials.
