Collision avoidance maneuvers (CAMs) for passive de-orbiting missions using sails are studied, maneuvering either the sail or the incoming object. Analytical expressions for the CAM are obtained leveraging the proximal motion equations, maximizing the total or b-plane-contained deviation, or minimizing collision probability. When the sail performs the CAM, different attitude-related strategies are investigated. Representative test cases are proposed using data from ESA's MASTER tool or conjunction data messages. The required amount of propellant or sail maneuverability as function of lead time is traded-off, and the evolution in time of the covariance matrix is investigated.

Abstract
Collision avoidance maneuvers (CAMs) for passive de-orbiting missions using sails are studied, maneuvering either the sail or the incoming object. Analytical expressions for the CAM are obtained leveraging the proximal motion equations, maximizing the total or b-plane-contained deviation, or minimizing collision probability. When the sail performs the CAM, different attitude-related strategies are investigated. Representative test cases are proposed using data from ESA's MASTER tool or conjunction data messages. The required amount of propellant or sail maneuverability as function of lead time is traded-off, and the evolution in time of the covariance matrix is investigated.| File | Dimensione | Formato | |
