SOXS

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.[1][2]

Features

[edit]
  • 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)[3]
