• Docking AP tweakable for min distance for gross horizontal adjustments (so it stays 100m away from the docking port until it is aligned and then comes straight in -- #234
• Rendezvous AP max closing velocity needs to be tweakable (100 m/s is very high)
• Rendezvous Autopilot should use RCS when close / when closing velocity is low.
• Rendezvous AP should use a proper state machine

Could the rendezvous autopilot benefit from a linearized gravity Hill-Clohessy-Wiltshire rendezvous/lambert solver like in Conway+Prussing, Orbital Mechanics, section 8.5 on Linear Impulsive Rendezvous?
