The ASE software allows autonomous operations in flight and has been successfully used on the Earth Observing-1 (EO-1) Mission. EO-1 is currently using this onboard decision-making software to change the satellite’s priorities without the involvement – or even knowledge – of ground controllers in order to observe unexpected environmental phenomena on the earth’s surface. Interface & Control Systems, Inc. (ICS) played a key role in the ASE software effort by providing both software engineering to the ASE team, as well as providing ICS’s product “SCL”.  The SCL software suite provides the architectural software components that enable plug-in autonomy agents such as Continuous Activity Scheduling Planning Execution and Replanning (CASPER) and Livingstone 2 to communicate with the SCL robust scripting executive to execute the agent’s directives in real-time.  Beyond providing an integration frameworks for other Artificial Intelligence technologies, SCL itself is built around a real-time Expert System capable of performing Fault Detection Isolation and Recovery (FDIR) for the spacecraft and subsystems.  SCL provides a full-featured scripting language and a command formatting capability for low-level device control.  Additionally, SCL provides a Rule-Based Expert System capable of on-board real-time monitor and control and autonomous reaction to changing data points.  The SCL system is flight-proven and had been on-orbit for more than 6 years on the NASA FUSE satellite.
