NAVIGATING A CREWED LUNAR VEHICLE USING LIAISON

摘要

This paper examines the benefits of navigating a crewed vehicle at the Moonusing both ground tracking and satellite-to-satellite tracking, where the trackingsatellite is stationed in a lunar halo orbit. Linked Autonomous InterplanetarySatellite Orbit Navigation (LiAISON) is a new technique that has been shownto dramatically improve the navigation of lunar satellites, libration orbiters, andEarth orbiting satellites using simple scalar satellite-to-satellite observations,such as range or Doppler. In this paper, LiAISON is applied to the problem ofnavigating a crewed vehicle in low lunar orbit. It has been found that addingLiAISON observations to a ground navigation solution improves the navigationenough to reduce the number of active ground tracking stations from six tothree.
