Current Research on a New Spacecraft Autonomy Architecture named Remote

Remote AgentPart 1 Introduction to Spacecraft AutonomyAbstractThis first composing of a two-part series introduces current research on a new spacecraft autonomy architecture, named Remote Agent, which applies artificial intelligence techniques to spacecraft control functions. The necessity for autonomy technology is nowhere greater than in deep space missions. Remote Agent is a model-based autonomous system being developed in a collaborative effort between the content Aeronautics and Space Administrations Jet Propulsion Laboratory and Ames Research Center. This spacecraft control scheme is be of three parts that work together 1) the Planner-Scheduler, 2) Mode Identification and Recovery, and 3) the Smart Executive. Models of the spacecrafts components and environment are given to Remote Agent and it figures out the necessary detailed operating procedures on its own. Because autonomy improves mission performance and reduces costs, autonomously controlled spacecraft will become mo re prominent in future space missions.IntroductionThe National Aeronautics and Space Administration (NASA) is being confronted with the challenge to perform more frequent and intensive space-exploration missions at greatly reduced cost. Nowhere is this more of the essence(p) than among robotic planetary exploration missions that the Jet Propulsion Laboratory (JPL) conducts for NASA. This paper describes current research on a new spacecraft autonomy architecture development artificial intelligence (AI) techniques to challenging computational problems in planning and scheduling, and real-time monitoring and control. Work on this software package combines research from diverse areas of AI such as model-based reasoning, qualitative reasoning, planning an... ...-122.2.
