Dynamical Issues in Space Situational Awareness
Abstract
We propose to conduct fundamental research in the field of Space Situational Awareness related to the topics of orbital and rotational dynamics, maneuver detection and constraints on active satellites, and probing fundamental constraints on uncertainty mapping in the space environment. Our goal is to bring a rigorous approach to the study of active and non-active space object dynamics to better understand the dynamics that shape their motion and the change events that active bodies are commanded to undergo. Results from this research program can be used to develop a better understanding of the evolution of a passive or active space object s state, how models of these effects can be estimated and improved. These studies will also lead to improved tracking strategies to enable the identification of hypothesized physical effects, improved modeling techniques to more accurately fit SSA observations, and the development of methods to analytically discern the actions of controlled space objects based on measurable quantities.Research methods used in this study rely on fundamental astrodynamics, optimal control and dynamical systems theory.Our proposed research has three components: 1) Resonant Dynamics: with a focus on complex andchaotic orbital and rotational dynamics due to interactions with external forcing. 2) Active Satellites: witha focus on constraining and predicting future actions of noncooperative but active space assets. 3)Fundamental Constraints: with a focus on understanding how the symplectic geometry of spacetrajectories places constraints on phase flow distributions, and how these can be leveraged.
