SRIHARIKOTA: The Indian Space Research Organization (
) on Wednesday successfully placed
– the second communication
meant primarily for
GSAT-7A is meant for augmenting the existing communications capabilities of satellites utilized by the Indian Air Force.
(Geosynchronous Satellite Launch Vehicle) carrying the satellite lifted off from the second launch pad at Satish Dhawan Space Center in
at 4.10pm It was the 13th flight of GSLV Mark II and the seventh flight with an indigenous cryogenic engine.

Around 19 minutes after take-off, the three-stage launcher ejected the satellite in a geosynchronous transfer orbit.
In the coming days, the satellite will move its final geostationary orbital slot at an altitude of around 35,000km by firing its onboard chemical propulsion system.
Isro chairman K. Sivan said GSLV had GSAT-7A in a super synchronous orbit achieving an altitude of 2,000km more than the intended slot. “We have three successful missions in 35 days,” he said
Sivan said during the today’s mission, the propile for the second stage was increased from 35.5 tons to 40 tons and cryo stage from 12 tons to 15 tons. “The cryo stage was also burnt to depletion. We have also used a Gregorian antenna to improve the performance of the satellite, ‘he said.
Vikram Sarabhai Space Center director S Somanath said, “The vehicle was 1.8metre taller than usual. To achieve that, our team meticulously worked on the design, load and control systems, analyzed and reviewed. ”
GSAT-7A – the 39th communication satellite of Isro – has communication capabilities to users in Ku-band over the Indian region.

GSAT-7A is expected to interlink all ground-based radars, airbases and airborne early warning and control aircraft for surveillance, maintain air superiority, gather intelligence by detecting aircraft, vessels and other vehicles in long range.
Why ISRO’s GSAT-7A is launching the Indian Air Force
Once GSLV-F11 (GSLV Mk II) rocket launches GSAT-7A satellite on Wednesday in the geo orbit, the communication satellite will enable the Indian Air Force (IAF) to interlink different ground radar stations, airbases and AWACS aircraft. It will boost the air force’s network-centric warfare capabilities and enhance its global operations.
The satellite is also expected to boost the IAF’s network-centric warfare capabilities, ie, linking all its platforms.
It will help drones conduct surveillance and satellite-controlled unmanned aerial vehicles (UAVs) improve their range and endurance to strike at the enemy’s targets from the long distance.
In September 2013, Isro launched Gsat-7 (Rukmini), a communications satellite exclusively for Navy to monitor the Indian Ocean Region up to 2,000 nautical miles and provided real-time inputs to Indian warships, submarines and maritime aircraft.
