摘要
随着GPS、GALILEO、GLONASS以及我国北斗导航定位系统的不断发展,基于多星座下的GNSS接收机自主完好性监测算法也已被国内外学者广泛研究。本文首先介绍了接收机自主完好性监测(RAIM)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 continuous development of GPS, GALILEO, GLONASS ,as well as China＇s Beidou navigation positioning system, the GNSS receiver autonomous integrity monitoring algorithm based on multi-constellation also has been widely studied beth at home and abroad. The paper first introduces the principle of receiver autonomous integrity monitoring （RAIM） algorithm, then the RAIM algorithm under the single-constellation, the combination of multi-constellation is respectively studied and simulated, graphics and data simulation results demonstrate the performance of integrity monitoring under the combination of muhi-constellation is superior to single-constellation.
