In this position, I worked on my undergraduate thesis: 'Development of the Radiation Tolerance of the CROSS Star Tracker'. This work was done in collaboration with Space Machines Company to investigate and mitigate the impact of radiation on the CROSS Star Tracker in longer-duration and more critical missions.- Identified relevant radiation effects and impacts on CROSS's electronics hardware, simulating the radiation environment, estimating total ionising dose and estimating single event effect rates. - Developed mitigation strategies for Single Event Upsets affecting memory devices, firmware, and the camera sensor.- Designed a power switching Single Event Latchup protection circuit. This work was presented at the 20th Australian Space Research Conference as a poster presentation.
