The Working of GSLV-7A

  • The GSAT-7A will connect all IAF assets like planes, air-borne early warning control platforms and drones with each other and ground stations, and work towards a network-centric warfare capability.

  • Gsat-7A is meant for augmenting the existing communication capabilities of satellites utilised by the Indian Air Force.

  • It will also reduce the possibility of snooping and leakage of information that’s possible while using satellites launched by foreign operators.

  • Around 19 minutes after take-off, the three-stage launcher ejected the satellite into a geosynchronous transfer orbit.

  • In the coming days, the satellite will be moved to its final geostationary orbital slot at an altitude of around 35,000km by firing its onboard chemical propulsion system.

Speech During the Launching Ceremony

  • In 35 days, this was the 7th mission by ISRO. Four Indian made satellites have been launched and 3 rockets have been successfully launched from Sriharikota.

  • The upgraded GSLV Mk II rocket “performed marvelously”

  • ISRO will launch 32 missions in 2019

  • The vice-president Congratulate ISRO for successfully launching the advanced communication satellite GSAT-7A, with launch vehicle GSLV-F11, from Sriharikota in Andhra Pradesh. The 2250 kg satellite built by ISRO will be a big boost to our defence capabilities.

Features of GSLV-7A

  • The 2,250-kg satellite is piggybacking on the GSLV MK II (Geosynchronous Satellite Launch Vehicle) which is powered by an indigenous cryogenic engine. This is the seventh flight of the rocket with Indian-made cryogenic engine.

  • Scientists said the satellite will have a mission life of eight years.

  • The Navy already has a similar satellite, the GSAT-7, which was launched in August 2013, said Navy spokesperson Captain.

  • It helps the Navy warships, submarines and maritime aircraft with inputs across the Indian Ocean region and safe communications capacity.

  • The two satellites, along with a third - the GSAT-6, will be the communications hub for the military.

  • The country already has a battery of earth-imaging CartoSAT series of satellites and a Hyperspectral Imaging Satellite that provide inputs to secure India’s borders.

  • India also gets data from Canada’s RadarSat 2 satellite that helps with natural disasters and resource management. It complements ISRO’s radar satellite RISAT-1, which is used for reconnaissance activities.

Usefulness for Indian Air Force

  • Once GSLV-F11 (GSLV Mk II) rocket launches Gsat-7A satellite 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, i. e. , 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 enemy targets from long distances.


  • Geosynchronous Satellite Launch Vehicle abbreviated as GSLV, is an expendable launch system operated by the Indian Space Research Organisation.

  • GSLV has been used in thirteen launches to date, since its first launch in 2001 to the most recent on December 19,2018 carrying the GSAT-7A military communications satellite


  • The Indian Space Research Organisation is the space agency of the Government of India headquartered in the city of Bengaluru.

  • Vision: “Harness space technology for national development while pursuing space science research and planetary exploration. “
