摘要
随着北斗导航系统的广泛推广和应用,其系统完好性问题也逐渐走到我们的视野里,如何保证北斗卫星的完好性则成为当前北斗系统亟待解决的问题。本文以卫星导航系统的完好性检测为背景,以北斗系统作为研究对象和平台,设计了针对北斗导航系统接收机的加权最小二乘的RAIM监测算法,并且通过已有的完好性检测设备采集数据进行算法验证,证明了该软件算法的准确性。
Along with the wide popularization and application of BeiDou navigation system,the problem of its system integrity gradually come to our vision,how to ensure the integrity of BeiDou satellite is becoming the problem that the BeiDou system needs to solve urgently.In this paper,based on the integrity detection of satellite navigation system,the North bucket system as the research object and platform,the RAIM monitoring algorithm for the weighted least squares of the BeiDou navigation system receiver is designed,and the accuracy of the software algorithm is proved by using the existing intact detection equipment to collect the data to verify the algorithm.
