Abstract
Spacecraft equipped with reaction wheels require momentum management as part of nominal on-orbit operations. When chemical thrusters are used for dumping momentum, the maneuver may disturb sensitive payload operations. This paper presents an angular momentum management algorithm for planning the optimal desaturation strategy that maximizes the time between maneuvers. The algorithm is derived by applying solutions to the minimum enclosing disk problem to reaction wheel arrays. The algorithm provides a general technique for planning desaturation maneuvers, in contrast to current methods which are either too complex or too mission-specific. Simulation results show that its application can nearly double the time between maneuvers with respect to percentage based desaturation techniques.
