The Department of Defense (DoD) is seeking proposals for the topic of "On-Orbit Intent Estimation of Close-Proximity Space Objects" as part of their SBIR 23.3 BAA. The objective of this work is to develop techniques that enable the estimation of a space object's behavior/intent in close-proximity scenarios. The goal is to analyze available data in the space domain to not only determine where an object is/going but also why it is there/maneuvering. The ability to estimate both an object's intent and its state simultaneously will enable more-informed decision-making in the space domain. The DoD is particularly interested in solutions that can be implemented on-board a spacecraft to enhance its autonomous capabilities. The project will be conducted in three phases: Phase I involves a comparative assessment and trade-off study of intent estimation approaches, Phase II focuses on improving and iterating upon the most promising method, and Phase III involves the development of flight-ready intent-estimation software. The solicitation is open until October 18, 2023. For more information, visit the SBIR topic link or the solicitation agency website.
