ELECTRONIC INSTRUMENTATION FOR THE GAMMA-RAY BURST EXPERIMENT ON STRETCHED ROHINI SATELLITE SERIES-C (SROSS-C) MISSION

The Stretched Rohini Satellite Series-C (SROSS-C) was launched into a near earth orbit by the Indian Augmented Satellite Launch Vehicle (ASL V-D3) on May 20, 1992. A gamma ray burst (GRB) experimental package fo r detecting and measuring temporal and spectral characteristics of cel estial GRBs was one of two main payloads onboard SROSS-C. A microproce ssor based electronics unit was designed and developed for payload dat a handling, control of payload operation in different modes, and telem etering burst data to ground stations. The electronic instrumentation functioned well during mission lifetime. Electronic instrumentation an d its satisfactory performance during the mission period are presented in this paper.
