A computer program previously developed at COMSAT Laboratories for general purpose solar array calculations has been adapted to model array performance for a number of operational geosynchronous communications satellites, such as MARISAT and INTELSAT V. The modeling was accomplished by taking the current-voltage characteristics of a single solar cell and using appropriate scaling factors to model the performance of the entire solar array. The predicted solar array output is then compared with actual flight performance data. To date, the solar array performances show good agreement with predictions based on trapped-electron radiation damage only.
