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.
