GNSS完备性监测研究

Research on the Integrity Monitoring of GNSS

GNSS完备性监测是目前研究的热点，本文分析了当前几种GNSS完备性监测手段的优缺点。针对北斗区域系统的特点，研究了基于GNSS快速精密星历的完备性实时监测方法，推导了相关公式。算例分析表明，该方法简单实用，能快速地监测卫星星历错误，能准确识别多系统多颗卫星的故障，扩展了北斗系统的监测范围，实现了GNSS完备性实时监测。

GNSS integrity monitoring is a research hotspot at present. The advantages and disadvantages of several current GNSS integrity monitoring methods are analyzed. Based on the characteristics of BeiDou regional system, the real - time multi - GNSS integrity monitoring method based on GNSS rapid precise ephemeris is studied and related formulae are deduced. The calculation result analysis shows that the method is simple and practical. It can rapidly detect satellite ephemeris error, accurately identify faults of multi system and multi satellite, expand the monitoring area of BeiDou system and realize the real - time GNSS integrity monitoring.
