Title

Precision Control of Microsatellite Swarms using Plasmonic Force Propulsion

Abstract

Scientific mission concepts using swarm formations require micronewton levels of thrust to enable precision formation flying and spacecraft pointing. Plasmonic force propulsion can provide these levels of thrust to the microsatellite platform to enable these advanced missions. Three case studies are used to evaluate the performance of a swarm composed of microsatellites, each equipped with plasmonic thrusters. Control techniques are evaluated and adapted to provide robust and precise control under system disturbances, model uncertainties, and noise. Results show that relative position and pointing can be achieved to meet scientific objectives for a range of swarm precision formation missions.
