摘要:民航导航中,对于导航系统的导航完整性有严格的要求。随着卫星导航系统在飞机上的应用,机载增稳系统或GPS接收机自主完整性监视越来越受到重视。本文主要针对GPS接收机自主完整性监视的算法进行研究。常用的自主完整性监视方法主要有:距离比较方法;最小二乘方法;奇偶法等。本文主要对最小二乘方法进行研究。

Abstract:The integrity requirements of the navigation system in civil aviation is very rigid. With the using of the satellite navigation system on board, people focus more on Aircraft-Based Augmentation System or RAIM. The more useful methods are: Range comparison integrity method; least-square residual method and parity method. We will discuss the least-square residual method in this article.
Key words:RAIM; HPL; alert time
