Rendezvous is an important part of current and future space missions. For example, in the Mars Sample Return (MSR) mission, there will be a rendezvous and capture manoeuvre in a Mars orbit where a passive container containing a soil sample must be captured by an orbiting chaser craft. There is strong motivation to perform such manoeuvres autonomously due to long communication delays, and tight tolerances. In addition, thruster propellant is a finite resource so must be used efficiently.

This talk will present the design and implementation of a model predictive control (MPC) system to autonomously perform a spacecraft rendezvous and capture operation from the point of target detection all the way until target capture. Propellant consumption is actively minimised in the presence of physical and operational constraints through the use of constrained optimisation.
