Abstract : The report describes the performance of the support systems aboard the DME-A satellite, i.e., the attitude control, attitude detection, telemetry, command, antenna, and power systems, all of which were developed, fabricated, and tested by the Applied Physics Laboratory of The Johns Hopkins University. The scientific results obtained from the experiments aboard the satellite are not discussed in this document. The Introduction and Spacecraft Design sections of this report are presented to familiarize the reader with the project implementations and the basic design of the DME-A satellite, respectively. The DME-A satellite continues to successfully fulfill its mission objectives and provide useful scientific data, even after exceeding by over four months the one-year useful operating lifetime for which it was designed.
