Key Facts of GSAT-11

  • GSAT-11 called Big Bird is indigenously developed by ISRO.

  • It weight 5854 kg making it heaviest Indian-made equipment that has been put into orbit.

  • It will provide high data rate connectivity to Indian mainland & islands users thru 32 user beams in Ku-band & 8 hub beams in Ka-band.

  • It is 3 to 6 times more powerful than any other ISRO’s satellite.

  • It will help provide satellite-based internet to remote places where cable-based internet cannot reach.

  • It will boost broadband connectivity to rural & inaccessible gram panchayats in country under Bharat Net Project, which is part of Digital India Programme.

When GSAT-11 Would Become Operational?

  • After 30-minute flight, GSAT-11 separated from Ariane 5 in elliptical Geosynchronous Transfer Orbit. Achieved orbit was very close to intended one.

  • Post-separation, ISRO’s Master Control Facility in Karnataka took over command & control of GSAT-11.

  • Scientists will now undertake phase-wise orbit-raising manoeuvres to place satellite in Geostationary Orbit (36000 km above equator) using its on-board propulsion systems.

  • GSAT-11 will be positioned at 74-degree east longitude in geostationary orbit.

  • 2 solar arrays & 4 antenna reflectors of GSAT-11 will be deployed in orbit.

  • Satellite will be operational after successful completion of all in-orbit tests.
