How to dock your satellites in 3 easy steps

During close range rendezvous, vehicles often perform a series of “hops” to get closer to their target. Source.

References worth checking out if you want more technical details:

  • Automated Rendezvous and Docking by W. Fehse. I consider this the bible of RPOD, as it starts from basic principles/concepts and explains the whole procedure very well. It’s a bit out-dated and focuses on ISS docking missions in LEO, but the fundamentals haven’t changed.
  • I’m reiterating the games I mentioned above: Spaceflight Simulator, Kerbal Space Program, and Simple Rockets 2 are all fantastic as they let you build an intuition for orbital mechanics and manoeurvres. Another fun browser game is on SpaceX’s own website: ISS Docking Simulator.
  • In terms of papers, the best ones I’ve seen are ones which go through entire mission concepts. Camille Pirat’s EPFL PhD thesis is great (along with many of his papers).
  • The papers about the CPOD mission and AAReST mission are great starting points too.
