Automated ISR Collection Management System

Gonsalves, P. and Cunningham, R. Proceedings of the 4th International Conference on Information Fusion, Montreal (August 2001) Here we describe an Automated ISR Collection Management System (AICMS) that can conduct dynamic multi-asset synchronization, tasking, and monitoring across multiple echelons. AICMS enhances the collection management process by extracting relevant key information from the available sensor stream […]

Navigability Evaluation and Visualization for Mars Rover Operations

Goodsell, T., Snorrason, M., Ruda, H., and Ablavsky, V. Proceedings of the International Conference on Visualization, Imaging and Image Processing, Marbella, Spain (September 2001) We have developed the Rover Obstacle Visualizer and Navigability Evaluator (ROVANE) as a navigability evaluation and visualization suite to assist in distributed mission planning for NASA Mars Rover missions. Since mission […]

Automated Obstacle Mapping and Navigability Analysis for Rover Mission Planning

Goodsell, T., Snorrason, M., Ruda, H., and Ablavsky, V. Proceedings of SPIE, Volume 4364, Aerosense, Orlando, FL (April 2001) One of NASA’s goals for the Mars Rover missions of 2003 and 2005 is to have a distributed team of mission scientists. Since these scientists are not experts on rover mobility, we have developed the Rover […]

Applying Adaptive Control and Display Characteristics to Future Air Force Crew Stations
