Abstract:

This note is a summary of the initial flight results of the Lincoln Experimental Satellite 8 LES-8 autonomous stationkeeping system. The autonomous stationkeeping system on LES-8 was activated between 7 July and 4 October 1976 for stationkeeping the satellite at 109.7 deg W longitude. The satellite acquired station without overshoot and maintained the station with an absolute accuracy of 0.06 deg. The fuel efficiency during this experiment in the overdamped mode was about 50.
