GSAT-8 ( INSAT-4G ) is a commercial communications satellite of the Indian Space Research Organization (ISRO) / ISAC of the GSAT series (from the Insat -4 series).

It was placed in geostationary orbit along with ST-2 on May 20, 2011 at 20:38 UTC with an Ariane 5 ECA from the Center Spatial Guyanais rocket launch site in Kourou .

The three-axis stabilized satellite with 24 Ku-band - transponders equipped and is on the position of 55 degrees East, the Indian subcontinent with television (DTH) and radio navigation services by a two-channel GAGAN system ( GPS Aided Geo Augmented Navigation care). It is equipped with two reflector antennas with a diameter of 2.2 m, a 0.6 m C-band antenna and a 0.8 × 0.8 m L-band helix antenna for the GAGAN system. It was developed and built on the basis of the I-3K satellite bus from ISRO in Bangalore and has a planned service life of more than 12 years.
