Overview
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.
