Abstract
Constellations of EO/IR space based sensors can be extremely valuable for space situational awareness. In this paper, we present trade-off analysis and comparisons of different Low Earth Orbit (LEO) EO/IR sensor platform constellations for space situational awareness tasks. These tasks include early observation of changing events, and localization and tracking of changing LEO orbits. We derive methods and metrics for evaluation, testing, and comparisons of different sensor constellations based on realistic models and computationally efficient methods for simulating realistic scenarios.
