Ensuring the sustainability of future space missions and maintaining continuous access to space necessitates a serious and proactive approach to addressing the space debris dilemma. One crucial measure that can be undertaken is actively protecting against space debris by implementing satellite collision avoidance manoeuvres. This thesis focuses on researching robust methods to perform such manoeuvres, with a particular emphasis on the guidance and control systems of manoeuvrable vehicles. The Starlink constellation is used in this research as a reference scenario, considering its popularity and extensive development, although the developed system is applicable to any satellite. The core of achieving successful manoeuvres lies in the creation of a robust guidance system. This system integrates convex optimisation algorithms with reference tracking mechanisms, enabling the autonomous execution of collision avoidance manoeuvres to be both robust and fuel-efficient. The outcomes of this research represent a significant advancement in space debris mitigation, enhancing space sustainability.

It has been over 50 years since man first set foot on the Moon and proved that mankind could extend its borders beyond Earth, and yet no permanent lunar outpost has been set yet. Similar to how the construction of larger ports allowed for the exploration of the New World in the Renaissance, human exploration of space requires infrastructure beyond that required for spaceships and launchers. As our only natural satellite, the Moon is the best choice for a permanent base, one that would be capable of refuelling interplanetary missions, providing plentiful resources for the needs of people on Earth, and giving opportunities for fundamental research...
