Abstract

A novel approach to on-obit system identification of satellite attitude control dynamics is presented. The approach is fully automated and will thus enable a variety of satellite applications, including high-performance proliferated constellations and modular payloads. The key enabling feature of the approach is the ability to estimate the uncertainty in the model and then perform additional data collections specifically to reduce the uncertainty. A prototype software implementation of the algorithm accurately estimated multiple structural modes in a CubeSat simulation and a CubeSat reaction wheel testbed in preparation for an on-orbit demonstration as part of the The Aerospace Corporation’s Slingshot 1 mission.
