Language and Toolset for Visual Construction of Programs for Intelligent Autonomous Spacecraft Control

The paper describes approach to Autonomous Fault Tolerant Intelligent Control of Spacecraft based on usage of Onboard Real-Time Interpreter of Integrated Control Programs, including special Diagnostic Routine. Rules of the Autonomous Control Program could be added or refined from Earth in operative manner by radio channel. Specially designed Visual Domain Specific Language allowing Control Logic Designers check, analyze and construct Rules in user friendly graphical environment excluding necessity to involve Software Developers. Proposed approach allows reducing of costs and labor consuming of Space Mission because of reducing of efforts needed for common-style Flight Control Software coding, multi-stage testing and support. Special Software Engineering Toolset that including Visualizer and Graphical Constructor of these autonomous control programs presented as well as the principles of its design and development. The Prototype of the Toolset has been successfully introduced at JSC Information Satellite Systems, Krasnoyarsk Region, Russia.
