Military communication satellite to be launched on December 19.
It is a Military communication satellite
Although all Indian communication satellites offer capacity to the armed forces, GSAT-7A will be the first one built primarily for the Indian Air Force (IAF) to qualitatively unify its assets and improve combined, common intelligence during operations.
This new space-based dimension adds color to the way the Indian Air Force interlinks, operates and communicates with its aircraft as they fly and with command centres on ground
This satellite using Ku bandwill enable superior real time aircraft-to-aircraft communication; and between planes that are in flight and their commanders on the ground.
It will also support aerial activities of the Army and the Navy when required.
The GSAT-7A incorporates Chemical Propulsion Systemto provide an operational mission life of a minimum of eight years.
Chemical propulsion will be used for orbit raising as well as for on orbit attitude correction
Sufficient redundancy is built into the Spacecraft for continued service.
The Geosynchronous Satellite Launch Vehicle – F11 (GSLV-F11), will undertake its 13th flight carrying the 35th Indian Communication satellite GSAT-7A built by the ISRO.
It will place the 2,250-kg GSAT-7A communication satellite into a geosynchronous transfer orbit.
GSLV – F11
It is ISRO’s fourth generation launch vehicle with three stages.
The four liquid strap-ons and a solid rocket motor at the core form the first stage.
The second stage is equipped with high thrust engine using liquid fuel.
The Cryogenic Upper Stage forms the third and final stage of the vehicle.
It would enhance by many times the coveragenow provided by ground communication systems such as radars and stations of the Army.
Out-of-sight and remote areas where ground infrastructure and signals are difficult would get into the critical information loop.
The satellite is expected to help the IAF interconnect with various ground radar stations, airbases and AWACS (Airborne Warning And Control System) aircraft.
Pilots can communicate much better with headquarters while they fly. Headquarters can receive data in real time.
