Advancing the SmallSat Digital Twin (SSDT) for Active Debris Removal Simulations

TMC Technologies (TMC), in partnership with the West Virginia Small Satellite (SmallSat) Center (WVSSC), has recognized a significant need for a mature simulation test bed (i.e., digital-twin) to evaluate and analyze space-based laser techniques for active debris remediation/removal (ADR). There is currently no simulation software suitable for performing space-based laser ADR research that provides as high-fidelity digital twin as TMC’s SmallSat Digital Twin (SSDT) software. In this SBIR Phase I titled Advancing the SmallSat Digital Twin (SSDT) for Active Debris Removal (ADR) Simulations, TMC is proposing to enhance the SSDT software such that it contains additional models (optical, multi-camera, radar, debris) that support ADR analyzes, specifically space-based lasers being the first application. The upgraded SSDT will function as a digital twin platform, proficient in assessing the efficacy of various ADR technologies and algorithms within a digital flatsat environment that incorporates actual spacecraft flight and ground operations software. Furthermore, we will develop a strategic course for the inception, validation, and integration of new instrument models into the SSDT, positioning it as an optimal tool for ADR feasibility studies, prototyping, and future SmallSat mission planning.
