The 2,250 kg communications satellite, GSAT-7A was launched from the Satish Dhawan Space Centre, Sriharikota. This satellite from ISRO will aid communication for Indian military.

The launch is the last this year, according to Dr K. Sivan, Chairman of ISRO, and Secretary of Department of Space. This is a dedicated mission for updating and increasing the capability of the country's defence forces. The GSLV F11 carried the 2250 kilogram GSAT-7A from the second launch pad of the Satish Dhawan Space Centre, Sriharikota. The satellite was spewed out within a few minutes after lift-off.  The GSAT- 7A is ISRO's 35th communication satellite and a third mission in just 35 days.

According to DD news, the rocket, GSLV F 11 is the fourth generation launch vehicle with three stages. The launch vehicle is powered by an indigenous cryogenic engine. This launch is its 13th flight.  The vehicle with a four liquid strap-ons and a solid rocket motor at the core form the first stage. The second stage is equipped with a high thrust engine using liquid fuel.

The cryogenic upper stage forms the third and final stage of the vehicle. The satellite will be taken into the geostationary or circular orbit using the on-board propulsion system and it will take a few days after the separation from the launcher to reach its orbital slot.
