The research objective is to demonstrate the utility of Active Pixel Sensors for application on Star Tracker devices. Active Pixel Sensors hold promise for space applications due to their small size, effectiveness against radiation, and on-chip processing. The research focus is on documenting and validating ground test equipment for these types of sensors. Through demonstrating the utility of a commercial sensor, the researcher will be able to work on ensuring the accuracy of ground tests. This contribution to the research community will allow for more capabilities and further research on improving performance of active pixel sensors.
