Low-Thrust Transfers Incorporated into POMDP Planning for On-Orbit Servicing

1 reports · 1 sources

Susmitha Patnala, Vincent Mousseau, and Adam Abdin published a paper modeling low-thrust (LT) orbital transfers into a partially observable Markov decision process (POMDP) for on-orbit servicing (OOS) mission planning. The state space adds the servicer spacecraft's remaining propellant to support mass updates; high-thrust transfers are modeled with a precomputed transfer matrix, while low-thrust transfers are represented by an analytical GEO phase model, with propellant consumption and maneuver feasibility computed for given transfer-duration alternatives. The study solves the problem with SARSOP in a simplified OOS scenario, compares high-thrust and low-thrust strategies, and quantitatively evaluates the feasibility and operational impact of the low-thrust option. The paper states that low-thrust transfers are represented by an analytical GEO phase model and are paired with preset transfer-duration alternatives.

  1. Integrating Low-Thrust Transfer Dynamics into POMDP Planning for On-Orbit Servicing Missions

    This research models low-thrust (LT) orbital transfers within a partially observable Markov decision process (POMDP) for on-orbit servicing (OOS) mission planning, adding the servicing spacecraft's remaining propellant to the state space to support mass updates. High-thrust transfers are modeled with a precomputed transfer matrix, while low-thrust transfers are represented by an analytical GEO phase model, with propellant consumption and maneuver feasibility computed for given transfer-duration alternatives. In a simplified OOS scenario, SARSOP is used to solve and compare high-thrust and low-thrust policies, quantitatively assessing the feasibility and operational impact of the low-thrust option.
