Paper Abstract

The Rendezvous Expert (RENEX) program simulates autonomous rendezvous and proximity operations during spaceflight for selected active vehicles and target vehicles. Space Shuttle mission flight rules were used as the basis for developing the knowledge base for trajectory planning/replanning and monitoring. Emphasis was on so-called "day of rendezvous" activities. The RENEX expert system software simulates real-time system monitoring as well as trajectory planning and software control functions. Conventional software simulates the vehicle guidance, navigation, and control functions. RENEX was developed to support streamlining operations for the Space Shuttle and Space Station programs and to aid definition of mission requirements for the autonomous portions of rendezvous for the Mars Surface Sample Return and Comet Nucleus Sample Return unmanned missions. The goal was to develop expert system technology which could be applied to operational decision support systems and/or to automating appropriate vehicle operations. The expert system and the insight it has provided into the development and the use of expert systems to achieve greater automation of rendezvous operations is discussed.
