2018 has been the busiest year with 17 flights and 2019 is going to be the busiest year with many launches of first-of-its-kinds. We can expect more questions from space in both Prelims and Mains.

GSAT-7A is the Indian Communication satellite built by ISRO. This is a geostationary satellite carrying communication transponders in Ku-band, it is built to provide communication capability to the users in Ku-band over the Indian region. Satellite using Ku band will enable superior real time aircraft-to-aircraft communication; and between planes that are in flight and their commanders on the ground.
- GSAT-7Ais an advanced military communications satellite meant primarily for the Indian Air Force with Indian Army using 30% of capacity.
- GSAT-7A is similar to Indian navy‘s GSAT-7and the Indian Air Force will be the sole operator of the satellite.
- GSAT-7A will be the first satellite built primarily for the IAF to qualitatively unify its assets and improve combined, common intelligence during operations.
- The satellite is expected to add a new space-based dimension to the way Indian Air Force interlinks, operates and communicates with its aircraft as they fly and with command centres on ground.
- GSAT-7A is designed to expand the communication capabilities of the Indian Air Force (IAF). It will do this by connecting many of the ground radar stations, airbases and aircrafts operated by the IAF, and is also expected to boost some of their network-dependant warfare and drone capabilities.
- It will be placed in its final geostationary orbit using the onboard propulsion systems.
- It comes with many firsts, including increased propellant loading and other features.
- The advanced communication satellite also came with new technology regarding the antenna to improve the performance.
- The satellite will enhance network-centric warfare capabilitiesof the Indian Air Force and therefore enhance its global operations.
- The satellite will also be used by Indian Army‘s Aviation Corps for its real-time control and communication system for the helicopters and UAV’s operations.
- This was the heaviest satellite lifted by the GSLV with indigenous cryogenic stage. (Not to confuse with GSAT-11, which is the overall heaviest satellite of India)
- Mission life of GSAT-7A is 8 years.
GSLV – F11 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 of the vehicle is equipped with high thrust engine using liquid fuel. The Cryogenic Upper Stage forms the third and final stage of the vehicle. This is GSLV Mk-II version. F11 is 11th operational flight.
