随着GNSS接收机技术的不断发展，基于多星座下的GNSS接收机自主完好性监测（RAIM）算法也已被国内外学者广泛研究。首先介绍了接收机自主完好性监测奇偶矢量算法的原理，然后分别对单星座、多星座组合下的RAIM算法进行了研究和仿真，图形化和数据化的仿真结果充分证明了多星座组合下的完好性监测性能优于单星座下完好性监测性能。

With the development of GNSS receiver technology,the GNSS receiver autonomous integrity monitoring (RAIM)algorithm based on multi-constellation also has been widely studied both at home and abroad. The paper firstly introduces the RAIM algorithm under the single-constellation and the combination of multi-constellation respectively,then carries simulations. Graphics and data simulation results testify the performance of integrity monitoring under the combination of multi-constellation is superior to single-constellation.
