Abstract
For several years, CNES has been working on Flight Dynamics algorithms to ensure high level of autonomy for next generation of space missions. One example of these autonomous techniques is the Autonomous Orbital Control, which consists of delegating to onboard satellite system the identification, planning and realization of orbital corrections to stay in the mission reference orbit. ASTERIA, an application of on-board autonomy combining station keeping and collision risk management for the low earth orbit satellites, enables both in-track and cross-track control for different LEO missions. The on-board collision risk management process is fully integrated into the autonomous station keeping in order to maintain the satellite orbit as best as possible and to minimize mission unavailability resulting from the avoidance maneuvers.
The paper aims to show the completeness of the ASTERIA concept. First, the principles of on-board orbit control with collision risk management are described with the operational concepts of such a solution. Then, the ability to operate ASTERIA is demonstrated through an in-orbit experiment performed last year on the ESA OPSSAT 3-Units CubeSat.
