Abstract:

The objective of this study was to perform basic research into the observable consequences of natural forces and commanded actions such as changes in orbit or attitude for resident space objects RSO in Earth orbit. By studying and developing improved models of these activities, the goal was to be able to identify their observable consequences and devise optimal ways in which they can be detected or constrained based on existing astrometric and radiometric observation techniques. These research goals were chosen as they would advance the application of the scientific method in Space Situational Awareness SSA and support the development of unambiguous observation strategies to properly characterize space objects.
