Coordinated Hyperspectral Imaging Nano-Satellite Networks for Space Situational Awareness.

摘要

This study has examined how to inspect Resident Space Objects (RSOs) using other Observer satellites, all of which are in fixed orbits. Optimal methods for determining which Observers should characterize each RSO at every sample time have been developed. The resulting inter-satellite measurements are typically at a sufficient range that an affine model of the imaging is highly accurate, so affine transformations have also been studied. Once these measurements are taken, they must then be transmitted to Earth through a communications network, thus congestion control and routing algorithms especially suited for this Space Situational Awareness task have been derived.
