Satellite Formation Design for Space Based Radar Applications

Abstract

There is much interest in relative formations in low Earth orbit for many different applications including distributed aperture systems and communications. Methods have been developed to create relative trajectories that do not fight the natural motion caused by oblateness perturbations. The formulas for these J2 Invariant formations are recast in terms of relative orbit parameters that facilitate formation design. Impulsive maneuver schemes have also been developed for relative trajectories but they do not allow for multiple maneuvers for tight control. In this report, a process is developed to create relative orbits that meet design criteria while also not fighting natural motion. A maneuver scheme is employed that allows for tight control and several maneuvers per orbit. A Monte Carlo simulation is performed to assess the performance of this guidance approach with navigation and control errors.
