  • Spacecraft solar cell monitoring system
    Patent number: 8180505
    Abstract: An onboard solar cell array current and voltage characteristic determination method is preferably used on small spacecraft and determines the solar cell orientation relative to the sun by a comparison between prelaunch solar cell characteristics with on-orbit solar cell characteristics well suited for spin axis determinations and monitoring the degradation of on-orbit solar cells over the operational life of a picosatellite.
    Type: Grant
    Filed: November 7, 2007
    Date of Patent: May 15, 2012
    Assignee: The Aerospace Corporation
    Inventors: Edward J. Simburger, Daniel L. Rumsey, Simon H. Liu, John S. Halpine
