Solar X-Ray Spectrometer, or SOXS, was an experimental payload launched onboard Indian geostationary satellite

GSAT-2 GSAT-2 was an experimental communication satellite built by the Indian Space Research Organisation (ISRO) and launched on one of the first GSLVs. The satellite was positioned at 48 deg east longitude in the geo-stationary orbit. Payloads GSAT-2 c ...

Features

* X-Ray Spectrometer (SOXS) was flown onboard

on 8-May-2003. * SOXS employs Si and CZT

semiconductor A semiconductor is a material which has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way. ...
