针对基于机载多传感器的水平导航实现问题,通过卫星自主完好性监控、导航传感器实际导航性能评估、飞行误差监控以及总系统误差监控技术的综合设计运用,使机载导航系统具备了所需导航性能的运行能力。针对国际民航组织提出的导航性能指标要求,采用西安咸阳机场到北京首都机场的真实航路进行了RNP仿真验证。结果表明,提出的方法能够满足在航路段RNP-4、最终进近段RNP-0.3性能要求。

This paper gives an application approach of an RNP navigation system based on multiple sensors in civil aviation.The navigation system achieves RNP operation capability by GPS RAIM technique,estimating actual navigation performance technique of navigation sensors,calculating flight technique error and monitoring total system error technique.According to International Civil Aviation Organization’s navigation performance requirements,this paper uses the actual civil aviation route from Xi’an Xianyang International Airport to Beijing Capital International Airport to carry out flight simulation.The result shows that the proposed scenario can satisfy the function and performance requirements of RNP-4 during En-route,and RNP-0.3 during the final approach.
