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. Payload: [11] [12] [13]
GSAT-7A: Launched in December 2018 for the exclusive military use for the Indian Air Force. [44] [45] GSAT-7A allows IAF to interlink different ground radar stations, ground airbase, aircraft to aircraft Real-time Control System, AEW&C aircraft such as Beriev A-50-based Phalcon and DRDO Netra.
The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

GSAT-7, is a series of satellites developed by Indian Space Research Organisation for the use of Indian Armed Forces. Two satellites in this series are currently functional (7 and 7A) and three more (7R, 7B, and 7C) are planned. The satellite is expected to be launched using a GSLV Mk II rocket. [4]
GSAT-7, the multi-band communication satellite named Rukmini [4] carries the payloads in UHF, C band and K u band.It is the first dedicated military communication satellite (unlike earlier dual use satellites) built by ISRO that will provide services to the Indian Armed Forces [5] with the main user being the Indian Navy.

The GSAT series of geosynchronous satellites is a system developed by ISRO with an objective to make India self-reliant in broadcasting services. The system includes a total of 168 transponders (out of which 95 are leased out to provide services to broadcasters) in the C, Extended C and K u bands, providing services to telecommunications, television broadcasting, weather forecasting, disaster ...
The L band (1 to 2 GHz) electronically scanned AEW and surveillance radar is located on a dorsal fin on top of the fuselage, dubbed the "top hat", and is designed for minimal aerodynamic effect. The radar is capable of simultaneous air and sea search, fighter control and area search, with a maximum range of over 600 km (look-up mode).
The first development flight of the GSLV (Mk I configuration) was launched on 18 April 2001 was a failure as the payload failed to reach the intended orbit parameters. The launcher was declared operational after the second development flight successfully launched the GSAT-2 satellite. During the initial years from the initial launch to 2014 the ...
