摘要

本文描述了一类飞机精确进近导航中GPS卫星轨道星历监测的充分方法。在没有卫星机动的情况下，基于先前验证的星历参数投影的监视器足以满足导航完整性和可用性要求。在预定的保持机动之后，没有先前验证过的星历表可用，因此需要基于测量的方法。验证了该监测系统的可行性。

Orbit ephemeris monitors for category I LAAS

This paper describes sufficient methodologies to monitor GPS satellite orbit ephemeris for Category I aircraft precision approach navigation. In the absence of a satellite maneuver, it is shown that a monitor based on the projection of previously validated ephemeris parameters is adequate to meet navigation integrity and availability requirements. After scheduled stationkeeping maneuvers, no previously validated ephemerides are available, so a measurement-based method is required. The feasibility of such a monitor is also established.
