摘要
Abstract
The ground integrity monitoring is the use of four or more of the precise coor- dinates of the stations monitoring the satellite to calculate the satellite ephemeris and clock errors. The method must meet the monitoring stations covering more than quadruple the conditions for autonomous navigation and regional distribution stations Navigation Satellite navigation systems can not achieve the full arc integrity monitoring. The cover does not meet the conditions for the satellite, based on inter-satellite link monitoring methods, the use of four or more satellites with a certain coordinate error of the satellite monitoring. By intersatellite ephemeris data and ranging data calculated SISMA, so the whole arc of the satellite navigation integrity monitoring.关键词
