Abstract :
BDD-IIR radiation environment detector data are used to calculate the expected solar array degradation for over 9 years of GPS orbit and compared with telemetered solar array data. The large discrepancy between the predicted and measured solar array output remains, thereby eliminating displacement damage as the sole damage mechanism to the solar arrays.
