Abstract
The capability of space-based sensors to collect images is directly related to the agility of the sensor. Increasing the sensor agility can be accomplished using optimal control; however, planning for the increased performance is required in order to increase the overall collection capability of a system. This dissertation demonstrates how optimal control yields a higher agility for a given spacecraft system, and presents a new and simple method to estimate the performance increase. New targeting equations are developed that define the sensor attitude, rate and acceleration required to collect a moving target. Operational maneuvers are defined and generated using optimal control. Finally, a new formulation for the time-varying image collection planning problem is presented by combining graph theory with optimal control into a hybrid optimal control architecture.
