Weighing 3,423 kg at lift-off, GSAT-29 is the heaviest satelliteto be launched from India. With a mission life of 10 years, it is the 33rd communication satellite built by ISRO.
It will be placed in a geostationary transfer orbit. At its closest point it will be 190 km above the Earth, and at its farthest it will be 35,975 km above the Earth.
According to ISRO, “GSAT-29 is a multi-beam, multiband communication satellite.” Its payloads are designed to mainly focus on connectivity to the users in the hilly and geographically inaccessible areas, especially those in Jammu & Kashmir and North Eastern regions of India.

It also carries a Geo High-Resolution Camera to aid in high-resolution imaging. For the first time, an optical communication payload will be utilised for data transmission at a very high rate.
ISRO’s Master Control facility at Hassan, Karnataka will take over the command and control of GSAT-29 soon after its separation from GSLV Mk III - D2.
With the success of this launch, the developmental phase of the GSLV Mk III vehicle programme will be complete and the vehicle’s operational phase will begin.
