The Multiple Autonomous Discrete Event Controllcrs for Constellations (MADECC) project is an effort within the National Aeronautics and Space Admidstcation Goddard Space Flight Center's (NASA/GSFC) Information Systems Division to develop autonomous positioning and attitude control for constellation satellites. It will be accomplisheded using traditional control theory and advanced coordination algorithms developed by the Johns Hopkins University Applied Physics Laboratory (JHU/APL). This capability will be demonstrated in the discrete event control test-bed located at JHU/APL. This projcct will be modeled for the Leonardo constellation mission. but is intended to be adaptable to any constellation mission. To develop a common software architccture, the controllers will only model very high-level responses. For instance, after determining that a manuver must be made, the MADECC system will output a triangle V (velocity change) value. Lower level systems must then decide which thrusters to fire and for how long to achieve that triangle V.
