The Autonomous Sciencecraft Experiment (ASE) will fly onboard the Air Force TechSat-21 constellation of three spacecraft scheduled for launch in 2004. ASE uses onboard continuous planning, robust task and goal-based execution, model-based mode identification and reconfiguration, and onboard machine learning and pattern recognition to radically increase(More)
The Autonomous Sciencecraft Constellation flight demonstration (ASC) will fly onboard the Air Force’s TechSat-21 constellation (an unclassified mission scheduled for launch in 2004). ASC will use onboard science analysis, replanning, robust execution, modelbased estimation and control, and formation flying to radically increase science return by enabling(More)
Directorate, we are developing architectures for commanding and controlling a cluster of cooperating satellites through autonomous software development for the TechSat 21 program (see the “TechSat 21” sidebar starting on page XX). Many space missions require large, monolithic satellites. This often results in costly, complex, failure-prone vehicles whose(More)
In spacecraft telemetry expert systems technology i s being used to manage the complexity generated by the increasing number of complex measurands. However, an uncontrolled proliferation of rules in an expert system can lead to maintenance and management problems of the system. A semi-automated tool, such as Pragati's MVP-CA (Multi-ViewPoint Clustering(More)
Air Force Research Laboratory's Distributed Architecture and Simulation Laboratory (DASL) is designed to support the development of new concepts in space systems. One new concept is AFRL’s TechSat 21 program. TechSat 21 is a cluster of formation-flying and cooperating satellites. TechSat 21 poses significant challenges to satellite operations. The ground(More)
The Air Force Research Laboratory is developing a spacebased sparse-array aperture system, called TechSat 21. The TechSat 21 experiment is a cluster of three satellites that will fly in formation and operate cooperatively to perform the function of a larger, single satellite. The payload chosen to demonstrate the TechSat 21 concept is radar. Doppler and(More)
This paper contains information on the general characteristics of the Control Data Corporation, MDM Communications Division M1000 Communications Message Switching System. It is the intent of this paper to discuss the analytic systems approach to the problem that led to the building of unique hardware and software to resolve the message handling functions.(More)
