Abstract

The Solar Array Paddle generation power of ADEOS-II satellite dropped suddenly. We have investigated the cause of the anomaly. The telemetry indicated the generation power dropped by 2 A-step. This corresponded in the generation power of each array circuit. No anomalous telemetry was found except for attitude when the anomaly occurred. FTA was carried out and the possible locations for the anomaly were identified; Solar Array Paddle or Solar Array Paddle Harness. The laboratory tests showed the possibility that sustained arcs occurred between harnesses and the heat produced by arcs destroyed the bundled harnesses.
