Tracking a Rogue Satellite for Photometric and Positional Information Project Site: Pacific Defense Solutions Mentor: Kawai Kuluhiwa, Dennis Liang & Dave Archambeault
Project Abstract: Galaxy 15, a television communications satellite, lost contact with its owner Intelsat in early April 2010. A malfunction believed to be prompted by a solar flare knocked the satellite out of its geostationary orbit, sending it on a drifting path in space. Now observations of this object are necessary to understand the threat that it poses to other operational satellites. We will be using two similarly configured optical systems to track and image Galaxy 15 for photometric and positional measurements. Each system is equipped with a 1024´1024 back-illuminated charge-coupled device (CCD), a focal reducer, and an eight-position filter wheel with Johnson BVRI and clear filters. One optical system is on Maui, and the other is in Albuquerque, NM. Both systems are capable of tracking Galaxy 15 autonomously through a network-tasking GUI. Calibrated satellite data will be automatically collected from these two systems and processed using software called Astrograph, which provides accurate positional and photometric information on the object. This data will help analysts understand how the uncontrolled drift of the Galaxy 15 satellite will affect other operational satellites.
