Abstract:
In the situation of future multi-constellation dual frequency, the integrity of services provided by Global Navigation Satellite System(GNSS) is analyzed. Simulation environment is designed for multi-constellation. The odd and even vector method is used to compute the integrity, which achieves distribution of global VPL. Simulation results show that, compared with present standard positioning service provided by Global Positioning System(GPS), the integrity of this system is better. It can meet the requirements of LPV-200 level service for civil aviation.

摘要： 在未来多星座双频情况下，对全球导航卫星系统提供的全球服务的完整性进行仿真分析，设计多星座的模拟环境，采用奇偶向量法进行完整性计算，从而获得全球VPL的分布情况。仿真实验结果表明，与现有全球定位系统提供的标准定位服务相比，该系统提供的服务的完整性更高，能够达到民航LPV-200级别的完整性要求。
