Mixed Open-and-Closed Loop Satellite Task Planning

Abstract

A key problem in earth observation using satellite-based sensors is to allocate the limited resources to achieve optimal performance. In the literature, several algorithms are proposed to handle this problem as an open-loop problem. Using a closed-loop formulation over an open-loop formulation would provide a better solution if the closed-loop solution could be implemented in real-time. However, an optimal closed-loop formulation may not be able to handle a medium or a large scale problem in real-time. In this work, we have proposed a mixed open-and-closed loop algorithm to handle the problem in real-time by taking the advantages of open- and closed-loop formulations. Simulation results illustrating the performance of the proposed algorithm are also presented.
