From Wikipedia, the free encyclopedia
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.
- Block Schematics of SLD Payload (SLED, SFE, SLE and SCE)
- SSTM Daily Tracking (0 to 189 degrees)
