The Department of Defense (DoD) is seeking proposals for the topic "Uncertainty Management for Space Domain Awareness of Non-Standard Threats" as part of the SBIR 23.3 BAA. The objective of this topic is to develop algorithms and methodology to improve the propagation of uncertainty for objects in the beyond-GEO region, which have highly nonlinear dynamics, stochastic excitation, and uncertain initial conditions. This technology is crucial for accurately assessing the threat posed by objects in this area, which can potentially threaten terrestrial and space-based assets. The project will have a Direct to Phase 2 (D2P2) structure, where Phase 1 proposals will not be evaluated. In Phase II, the focus will be on developing algorithms to characterize uncertainty propagation, evaluating the impact of maneuvers and sensor exclusion, and identifying estimation techniques. The project will also explore dual-use applications and transition strategies based on operational USSF requirements. The topic is restricted under ITAR or EAR regulations, and offerors must disclose any proposed use of foreign nationals. Relevant keywords include beyond-GEO, xGEO, cislunar, space traffic management, space domain awareness, uncertainty propagation, orbit determination, and space sensor tasking. The solicitation is closed, and more information can be found on the DoD SBIR website.
