Control and State Estimation Techniques for the M-Sat Mission
Fractionated spacecraft is a current topic of research in low Earth orbit spaceflight. Atmospheric drag and tight tolerances dictated by scientific objectives make accurate state estimation and precision control essential to mission success. This is especially true for small spacecraft that are mass, power, and fuel restricted. This paper discusses a comparison between multiple control techniques for the M-SAT mission, a leader-follower mission with a 50 meter in-track formation. The controllers are evaluated based on position accuracy, fuel expenditure, and robustness in the presence of measurement noise. Also discussed is a comparison between two orbit state estimators to determine accuracy in the presence of large measurement noise.
