For Prelims and Mains: Features, objectives, scientific goals and significance of the mission.

 

Context: ISRO is gearing up for the launch of its latest communication satellite, GSAT-7A aboard Geosynchronous Satellite Launch Vehicle (GSLV-F11) on December 19, 2018 from Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh.

 

GSLV-F11:

The GSLV-F11 is ISRO’s fourth generation launch vehicle with three stages. The launch vehicle, which is in its 13th flight, will inject GSAT-7A into a Geosynchronous Transfer Orbit (GTO).

 

About GSAT-7A:

GSAT-7A would be placed in the geostationary orbit and this communication satellite is expected to help the IAF to interlink different ground radar stations, airbases and AWACS (Airborne Warning And Control System) aircraft. The idea is to improve the IAF’s network-centric warfare capabilities.

The GSAT-7A is expected to have the Ku-band transponders and two deployable solar arrays onboard.

  • The GSAT-7A is also expected to be a big push for drone operations as it will help the Navy reduce the reliance on on-ground control stations and take satellite-control of military unmanned aerial vehicles (UAV) which should help boost the range and endurance of the UAVs.
  • In addition to GSAT-7A, the IAF would also be getting the GSAT-7C in a few years, to boost the network-centric operations.

 

Background- GSAT 7 series:

The GSAT 7 series was launched in 2013 as a dedicated communications satellite for the Indian Navy, which made the Navy completely independent of relying on foreign satellites for its blue water capabilities, thanks to GSAT 7 having a 2,000 nautical mile footprint. This helps in providing real-time inputs to Indian warships, submarines and maritime aircraft.
