Military communications satellite
GSAT-7A is an advanced
military communications satellite meant primarily for the
Indian Air Force with
Indian Army using 30% of capacity.
[5]
Overview
GSAT-7A allows
IAF to interlink different ground radar stations, ground airbase, aircraft to aircraft
Real-time Control System ,
Airborne early warning and control (AWACS) aircraft such as
Beriev A-50
Phalcon and
DRDO AEW&CS . The satellite enhances
Network-centric warfare capabilities of the Indian Air Force and its global operations.
[6]
[7] The satellite is also used by
Indian Army 's Aviation Corps for real-time control and communication of its aviation operations.
[1]
[8]
[9] India is in the
process of acquiring high-altitude and long endurance satellite-controlled UAVs, such as American armed
Predator-B or
Sea Guardian drones, that can fire at enemy targets from long distances.
[7]
As of December 2018, there are 320 dual use or dedicated
military satellite in the sky, half of which are owned by the United States, followed by Russia, China and India (14).
[7] To boost its network-centric operations, the IAF is also likely to get another satellite GSAT-7C within a few years.
[7]
The GSAT-7A, with a mission life of 8 years, is also equipped with the
payload of 10
Ku band transponders,
[6] which offers
several advantages over c-band, such more powerful
satellite uplink and downlink signals ,
smaller antennas , and
non-interference of communication signals with
terrestrial
microwave systems .

Launch
GSAT-7A weighing 2,250 kilograms (4,960 lb) was successfully launched on 19 December 2018 by
GSLV Mk II F11 rocket from
Second Launch Pad of
Satish Dhawan Space Centre .
[13] This three-stage launch vehicle 51 meters tall, has a lift-off mass of about 421 tonnes and indigenously developed
cryogenic stage.
