The untracked orbital debris environment has been described as one of the most serious risks to the survivability of satellites inhigh-traffic low Earth orbits, where acute satellite population growth is taking place. This poster describes a method for correlatingobserved satellite orbital changes with orbital debris impacts, and demonstrates how populations of small debris (< 1 cm) can becharacterized by directly examining the orbit and attitude changes of individual satellites within constellations. The poster alsopresents means for detecting unusual movements and other anomalies (e.g., communication losses) in individual satellites andsatellite constellations using the Space Surveillance Network, other space surveillance sensors, and in situ methods. Finally, theposter discusses how an anomaly data archive and policy repository might be established, supporting an improved definition of theorbital debris environment in harmony with the Presidents Space Policy Directive 3.
