Preliminary test results for the CellSaver concentrator in geosynchronous earth orbit

A flight experiment to evaluate ABLE Engineering's CellSaver concentrator solar array technology was launched into geosynchronous earth orbit (GEO) in the beginning of 2004 on a Space Systems Loral satellite. This paper presents the experiment design, the ground test qualification program and preliminary on-orbit test results. The on-orbit data includes both temperature and power measurements from the first 9 months of the successful experiment.
