  • GSLV F-11 is the seventh flight of GSLV Mk-II and is equipped with indigenously developed cryogenic upper stage engine.
  • The satellite is nicknamed as ‘angry bird’ as it will enhance Indian Air Force (IAF) capabilities.
  • It is heaviest satellite launch in GSLV’s Mk-II version launch vehicle.
  • In September 2013, Isro launched GSAT-7 (Rukmini), a communication satellite exclusively for Navy to monitor Indian Ocean Region up to 2,000 nautical miles and provide real-time inputs to Indian warships, submarines, and maritime aircraft.

Significance

  • The satellite will give a boost to the strategic communication and networking capabilities of the IAF.
  • GSAT-7A will enable superior real-time aircraft-to-aircraft communication and between aircraft and base station.
  • GSAT-7A is expected to boost the IAF’s network-centric warfare capabilities by interlinking all ground-based radars, airborne early warning and control aircraft for surveillance, maintain air superiority, gather intelligence by detecting aircraft, vessels and other vehicles in long range.

GSAT-7A

  • Weight: 2250 Kg
  • Orbit: Super Synchronous Orbit (Orbit beyond Geosynchronous Orbit)
  • Mission Life: 8 years
  • GSAT-7A is the 35th communication satellite built by ISRO.
  • GSAT-7A is an advanced communication satellite with a Gregorian Antenna.
  • The satellite will operate in the Ku band (This frequency range is often used for satellite communications).
