GSAT-2 was an experimental communication satellite launched on the second test flight of India's GSLV in May 2003. Besides its transponders, it carried four small science experiments.
No longer operational, according to the public satellite catalogue.
GSAT-2 carried four C-band transponders, two Ku-band transponders and a mobile satellite service payload that used S-band one way and C-band the other.
It also carried four experiments: a radiation dose monitor, a surface charge monitor, a solar X-ray spectrometer (SOXS) for studying solar flares, and a radio beacon (CRABEX) for studying the ionosphere. It was placed at 48° E in geostationary orbit.
GSLV-D2 launched GSAT-2 from Sriharikota on 8 May 2003. It was the second development flight of GSLV and it carried a heavier satellite than the first.
To lift more, ISRO loaded more propellant into the core solid motor and used higher-pressure engines in the liquid strap-ons and the second stage. The third stage was a cryogenic stage bought from Russia. The rocket placed GSAT-2 in a geosynchronous transfer orbit of 180 km by 36,000 km.
