We derive new algorithms for Low Earth Orbit (LEO) event estimation based on joint search and sensor management of space based EO/IR sensors. Our approach is based on particle representation of hypothesized probability densities and the Posterior Expected Number of Objects of Interest sensor management objective function. We address scientific and practical challenges of this LEO estimation problem in the context of space situational awareness. These challenges include estimating changes in satellites trajectories, estimating current trajectories (localization), and estimating future collisions with other LEO space objects. Simulations and the results obtained using actual LEO satellites are presented.
