Experimental Demonstration of an Algorithm to Detect the Presence of a Parasitic Satellite

This is a AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH SCHOOL OF ENGINEERING AND MANAGEMENT report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A332314. The abstract provided by the Pentagon follows: Published reports of microsatellite weapons testing have led to a concern that some of these "parasitic" satellites could be deployed against US satellites to rendezvous dock and then disrupt, degrade disable or destroy the system. An effective detection method is essential. Various sensing solutions were investigated including visual, impact, and dynamic techniques. Dynamic detection, the most effective solution, was further explored. A detection algorithm was constructed and validated on the Air Force Institute of Technology's ground-based satellite simulator, SIMSAT. Results indicate that microsat microsatellites rigidly connected to a satellite can be detected with a series of small identical maneuvers utilizing data available today. All algorithm variations readily detected parasite-induced moment of inertia changes of 3-23%. The most accurate detection scheme. The most accurate detection scheme estimated the moment of inertia to 0.67%. The results look promising for sensing potential microsatellite threats to US systems. The detection scheme presented could easily be integrated into a complete space situational awareness system.
