LEO constellations of satellites are going to be a reality soon, increasing substantially the risk of collision. To cope with this known issue, autonomous and guaranteed onboard orbit control are deemed necessary. ESA is developing a technology to allow completely autonomous onboard control of a LEO satellite in order to ensure that the satellite remains within a space corridor of 10-20 meters in radius with respect to a predefined orbit. This thesis, which shall be held in collaboration with ESA, aims to study in detail this concept and implement a hardware-in-the-loop simulator in the ESTEC Radio Navigation Laboratory, connecting real space hardware (GNSS spaceborne receiver engineering model) with Radio Frequency Constellation Simulator and on-board satellite AOCS.
During the thesis, the candidate is expected to spend a period of two to three months in ESA/ESTEC (Noordwijk, the Netherlands) for arranging and testing the solution in the laboratory.
