Countdown begins for launch of communication satellite GSAT-7A

The 26-hour countdown is progressing smoothly for the launch of GSLV F 11 carrying GSAT 7A at the Space research Centre Sriharikota. Officials said that the process of propellant filling of liquid strap-ons had begun.

The last launch of this year is a dedicated mission for updating and increasing the capability of the Country’s defence forces. GSLV F 11 will carry the 2250 kilogram GSAT 7A from Sriharikota at 4.10 pm this evening.

The rocket will spew out the satellite within 20 minutes after lift off from the second launch pad of the Satish Dhawan Space Centre. “GSAT 7A is ISRO’s 35th communication satellite and it is the third mission in just over a month by the space agency.

The rocket, GSLV F 11 is the fourth generation launch vehicle with three stages. The 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 onboard propulsion system and it will take a few days after the separation from the launcher to reach its orbital slot.

The satellite is said to network-dependent warfare capabilities, enhancing its abilities to operate globally. ISRO had already launched GSAT 11, the heaviest communication satellite was launched from French Guiana on the 5th of this month.
