Time-Optimal Collision Avoidance Via a Greedy Polynomial Backward Sweep
Zeno Pavanello, Frank De Veld, Roberto Armellin
Spacecraft collision avoidance for low-thrust satellites often requires determining not only how to maneuver, but also how late a maneuver can begin while still ensuring safety. Th…
CAMmary: A Review of Spacecraft Collision Avoidance Manoeuvre Design Methods
Zeno Pavanello, Luigi De Maria, Andrea De Vittori +3
Ensuring safety for spacecraft operations has become a paramount concern due to the proliferation of space debris and the saturation of valuable orbital regimes. In this regard, th…
Collision Avoidance Maneuvers Optimization in the Presence of Multiple Encounters
Zeno Pavanello, Laura Pirovano, Roberto Armellin +2
The optimization of fuel-optimal low-thrust collision avoidance maneuvers (CAMs) in scenarios involving multiple encounters between spacecraft is addressed. The optimization's obje…
Recursive Polynomial Method for Fast Collision Avoidance Maneuver Design
Zeno Pavanello, Laura Pirovano, Roberto Armellin
A simple and reliable algorithm for collision avoidance maneuvers (CAMs), capable of computing impulsive, multi-impulsive, and low-thrust maneuvers, is proposed. The probability of…
