This code accompanies the paper "Manipulator-based Spacecraft Capture and Simultaneous Stabilization Using Deep Reinforcement Learning Guidance," submitted for possible publication in the Journal of Guidance, Control, and Dynamics.
A D4PG Implementation for manipulator-enabled spacecraft, tasked with capturing and stabilizing a piece of space debris. Trained entirely in simulation, it was then deployed to the Spacecraft Proximity Operations Testbed experimental facility at Carleton University.
This code uses Tensorflow 1.15.0
To run: python3 main.py
The default training run will produce a chaser spacecraft the captures and simultaneously stabilizes a target spacecraft. Videos will be produced as well. Good results should be obtained after roughly 14 days.
A pre-trained model and accompanying videos are found in the `Trained model' folder
