Abstract

The optimal configuration of satellite formations consisting of a telescope and multiple occulters around Sun-Earth L2 Halo orbits is studied. Focusing on the Quasi-Halo orbits, which are of interest for occulter placement, the phase space around L2 is examined. Trajectory optimization of the occulter motion between imaging sessions of different stars is performed. This enables the transformation of the global optimization problem into a Time-Dependent Traveling Salesman Problem (TSP). First, the TSP is solved for a simpler formation consisting of a telescope and a single occulter. Using dynamical insight around L2, approximate initialization regions of the occulter formation are identified. Combining the initialization and the methods developed for single occulter formation, a solution to the full TSP is obtained, which will enable a trade-off study of multiple occulters in terms of cost and scientific achievement.
