Optimal in-plane orbital evasive maneuvers using continuous thrust propulsion

Abstract

Introduction I N recent years, much research has been accomplished on optimal maneuvering in space using impulsive and continuous thrust to address problems such as orbit transfer, stationkeeping, and rendezvous. Very little research, however, has addressed the optimal intercept/avoidance problem, which relates directly to antisatellite, space reconnaissance, and collision-avoidance objectives. The optimal intercept/avoidance problem is becoming more relevant to spacecraft mission planning because of current and emerging capabilities to intercept and avoid interception. Where time permits, any target under intercept might be maneuvered to attempt to prevent a successful intercept. This option motivates this study of optimal evasive-maneuver strategies using a continuous low thrust propulsion system.
