Since the 2007 Chinese anti-satellite missile test, Space Debris has become a dominating talking point within the space community, prompting initiatives like the European Space Agency's Space Situational Awareness (SSA) program – started in 2009 - to track and catalogue fragments and leftover upper stage structures. This study aims to develop a tool capable of simulating images of debris captured from a satellite operating from a Sun-synchronous orbit, to develop software prior to launch that enables the onboard processing of this particular image data. To accomplish this objective, a Python-based tool was developed following an object-oriented programming approach. The tool integrates crucial data sources, including the GAIA Star Catalogue, which provides accurate positions and brightness information of stars, and the SPOOK object propagator for propagation of synthetic debris objects.
