Characterizing Highways and Automated Navigation in Cislunar Environment (CHANCE)
Abstract
This proposed effort is focused on a set of foundational mathematical and computational developments to enhance the capabilities to operate successfully in cislunar space within the context of space domain awareness. The seamless integration of systems for trajectory planning, control, and navigation given uncertain conditions is the key element of this proposal entitled “Characterizing Highways and Automated Navigation in Cislunar Environment (CHANCE).� The team’s strategy is based on (semi-)analytical approaches and computationally efficient algorithms for improved understanding of spacecraft motion in the XGEO multi-body environment and, given uncertainties, leveraging these insights for accurate navigation, trajectory planning and control throughout the cislunar regime. The team’s approach to infuse the control and navigational algorithms with knowledge of the unique dynamical features in this regime will enable the tracking and guidance responses that can adapt to the evolutionary nature of the environment. As the foundational behaviors are initially examined within environments that highlight specific dynamical elements for ease of mathematical representations, the value to the navigation and guidance algorithms resides in the persistence of these dynamical structures as the environment evolves. These realities demand an assessment of the critical dynamical behaviors as the environment evolves to higher fidelities. This project aims to address the challenges that lie at the discipline boundaries for dynamical systems theory, and uncertainty quantification to facilitate safe and responsive execution. The multi-institution team is led by recognized leaders that have enabled pioneering advances in the fields of astrodynamics, multi-body dynamics under models of varying fidelity, trajectory path planning, uncertainty quantification, adaptive control as well as control under uncertainty for various space systems. The team is truly diverse in expertise and experience with productive collaborations involving DoD, NASA as well as commercial scientists and engineers. Additionally, this collaborative research will involve students as active participants.
