The first step of any active debris removal (ADR) mission is the selection of the target. The
optimal choice is to find the most dangerous debris that can be removed considering the …

The recent decades have witnessed a tremendous growth in the number of satellites and
debris in space, leading to an increasingly high risk of collision between space objects …

Spacecraft formation flying and satellite cluster flight have seen growing interest in the last
decade. However, the problem of finding the optimal debris collision avoidance maneuver …

Abstract Calculating the Time of Closest Approach (TCA) and the minimal distance between
two orbiting objects is a vital step in space debris collision risk assessment and avoidance …

Space-based sensing is likely to increase in prevalence in the coming years, yet challenges
still exist from a sensor management perspective. To address this we use modelling …

In view of the high value of space assets and a growing space debris population, collision
analysis is of great significance. Collisions between space objects can, at best, be …

Collisions between Earth orbiting satellites and debris have been a topic of growing concern
among satellite operators and governments for many years. At the heart of preventing …

The overpopulation of the space enviroment is causing an increasing number of close
approach events, which poses a significant threat to operational satellites. Mitigating the …

In this paper, constrained minimization for the point of closest approach of two conic sections
is developed. For this development, we considered the nine cases of possible conics …
