ABSTRACT:
A satellite attitude/orbit control system (300) for managing a satellite cluster (200) in a satellite constellation (207). A satellite cluster (200) comprises a master satellite (203) and secondary satellites (201, 202, 204, 204). The master satellite (203) receives sensor data from secondary satellites (201, 202, 204, 204) and combines such secondary sensor data with master sensor data from a master satellite (203) to calculate attitude/orbit estimates for all satellites within the satellite cluster (200). Attitude estimates are forwarded to each satellite for initiation of attitude/orbit control. Each satellite cluster (200) subordinates to a constellation master satellite (301) for receiving additional attitude/orbit estimates for use in determining and controlling satellite attitude/orbits.
