Abstract
This paper investigates the numerical optimization of a collision avoidance maneuver and phase return for a satellite in a constellation network. The time until collision and return time are varied, and three impulse maneuvers are assumed. The total Delta-V is minimized while avoiding the collision by 1 km or greater and returning to the original satellite orbit phase. For this analysis, the Clohessy-Wiltshire (CW) solutions were utilized to linearize the system of equations for relative orbital motion without perturbation assumptions. Results demonstrated that a greater time until collision generally produces minimized Delta-V options but longer total maneuver times as a tradeoff.
