Max Cerf

TL;DR
This paper presents an optimization method for planning space debris removal missions, combining combinatorial and functional optimization to select debris and optimize trajectories, demonstrated on a case of removing five SSO debris objects.
Contribution
It introduces a novel iterative optimization approach that integrates debris selection and trajectory planning for space debris removal missions.
Findings
Method effectively optimizes debris removal paths.
Applicable to varying numbers of debris and mission durations.
Demonstrated on a case of removing 5 debris objects from 11 candidates.
Abstract
A possible mean to stabilize the LEO debris population is to remove each year 5 heavy debris like spent satellites or launchers stages from that space region. This paper investigates the DeltaV requirement for such a Space Debris Collecting mission. The optimization problem is intrinsically hard since it mixes combinatorial optimization to select the debris among a list of candidates and functional optimization to define the orbital maneuvers. The solving methodology proceeds in two steps : firstly a generic transfer strategy with impulsive maneuvers is defined so that the problem becomes of finite dimension, secondly the problem is linearized around an initial reference solution. A Branch and Bound algorithm is then applied to optimize simultaneously the debris selection and the orbital maneuvers, yielding a new reference solution. The process is iterated until the solution stabilizes…
