Solar X-Ray Spectrometer, or SOXS, was an experimental payload launched onboard Indian geostationary satellite GSAT-2 by the Indian Space Research Organisation, ISRO. SOXS collected data about X-ray emissions from solar flares with high energy and temporal resolutions.
Features
X-Ray Spectrometer (SOXS) was flown onboard GSAT-2 on 8-May-2003. SOXS employs Si and CZT semiconductor devices, which are extremely high resolution and low noise detectors. Detector package is mounted on a Sun Pointing Mechanism with tracking accuracy better than 0.1 degree. Pulse Height (PHA) measurements in 256 channels. System Dead Time- 16 microseconds for Si Pin and 13 microseconds for CZT. Energy window counters. On board calibration using Cd109 Radio isotope. System Health Parameters Monitoring. Onboard selection for Background Rejection (LLD/Threshold). In view of Temperature sensitivity of the detectors, observational interval is < 3 Hrs starting from 04:00 to 06:45 UT.
