Advanced Uncertainty Propagation for Space Situational Awareness
Title: Advanced Uncertainty Propagation for Space Situational Awareness
When: 16 March, Monday, 5-6 pm
Speaker: Brandon A. Jones, Associate Professor, The University of Texas at Austin
Abstract:
Space Situational Awareness (SSA) requires accurate prediction and estimation of a space-object catalog to identify risks to existing missions, detect anomalous events in the space domain, and ensure a safe environment for future operations. This requires an interdisciplinary approach to SSA that leverages astrodynamics, information fusion, statistical and data sciences, and other fields of engineering and mathematics. This presentation highlights recent work in computationally efficient, multi-fidelity uncertainty propagation for improved SSA, which leverages a hierarchy of satellite force models to reduce computation time in probability density function propagation. Such tools may be leveraged for multi-target tracking with >100,000 space objects, uncertainty propagation in the potentially chaotic dynamics found in cislunar space, and robust maneuvering target tracking with temporally sparse observation data. This talk will also provide a high-level discussion of other research at UT-Austin, including the SCOPE-1 satellite mission to demonstrate terrain-relative navigation technologies using a 3U cube satellite.
