A Demonstration of Robust Planning and Scheduling in the Techsat-21 Autonomous Sciencecraft Constellation

The demonstration (ASC) will fly onboard the Air Force’s TechSat-21 constellation (an unclassified mission scheduled for launch in 2004). ASC will use onboard science analysis, replanning, robust execution, model-based estimation and control, and formation flying to radically increase science return by enabling intelligent downlink selection and autonomous retargeting. Demonstration of these capabilities in a flight environment will open up tremendous new opportunities in planetary science, space physics, and earth science that would be unreachable without this technology. We offer a demonstration of the planning, scheduling, and execution framework for this application.
