The collision probability computation of space objects plays an important role in space
situational awareness, particularly for conjunction assessment and collision avoidance …

There have been several recent high-profile space events, notably the conjunctions of the
Aeolus and Starlink spacecraft (both maneuverable) and the IRAS and GGSE-4 spacecraft …

A method to compute fuel optimal maneuvers for long-term encounters is presented. The
maneuver design is formulated as a convex optimization problem employing lossless …

This work presents a sequential convex program method to compute fuel-optimal collision
avoidance maneuvers for long-term encounters. The low-thrust acceleration model is used …

This work presents a novel approach for the optimization of fuel-optimal collision avoidance
maneuvers (CAMs) in scenarios involving multiple encounters. The considered risk …

Conjunctions between spacecraft are increasingly common across orbital regimes,
demanding reliable and efficient collision avoidance (CA) strategies. The typical solution to …

The optimization of fuel-optimal low-thrust collision avoidance maneuvers (CAMs) in
scenarios involving multiple encounters between spacecraft is addressed. The …

SURVIVABILITYagainst the threat of collisions is a fundamental concern for the operation of
space vehicles, whether this entails managing individual or multiple spacecraft that operate …

The probability that two satellites overlap in space at a specified instant of time is called their
instantaneous collision probability. Assuming Gaussian uncertainties and spherical …

Because of the increasing number of objects in low Earth orbit, the fast and reliable
estimation of the collision risk is an important challenge for spacecraft owners/operators …
