Improved Dynamics Modeling of Proximity Flight using Relative Orbit Elements
Abstract
The proposed research responds to the pressing need of the Air Force to better understand and utilize the dynamics of satellite relative motion for close-proximity missions. Current closed-form relative dynamics models are typically ad-hoc, mission-specific, and affected by major limitations such as the inter-satellite range of applicability, the eccentricity of the satellites orbits, the type of modelled perturbation forces, the resulting algorithm complexity and computational load. The project goal is to develop novel, efficient and accurate relative dynamics models for proximity operations that can be effectively used for orbit design, and guidance, navigation and control (GN and C) in a broad range of mission scenarios. Those scenarios include orbits of arbitrary eccentricity at small to large distances from Earth (e.g., from low-Earth to geostationary orbits) and with inter-spacecraft separations from virtually zero to hundreds of kilometers.
