Bengaluru: The Indian Space Research Organisation (ISRO) is set to launch a path breaking communication satellite GSAT- 19 from the Second Launch Pad at Satish Dhawan Space Centre, SDSC SHAR, Sriharikota on Monday at 17:28 Hrs (IST). The GSAT-19 satellite is expected to fulfill Prime Minister Narendra Modi’s ‘ Digital India’ dream as it would change the way communication is being done in the country.

ISRO’s series of communication satellites started with the name INSAT ( Indian National Satellite) series. The new generation of INSATs is now named as GSATs (Geo Synchronous Satellites). The primary purpose of both the INSAT and GSAT series is communication and broadcasting services.

India’s heaviest rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III-D1) weighing 640 tonnes would be launching the communication satellite GSAT- 19 with a lift-off mass of 3,136 kilograms. This will be the heaviest satellite being launched from India till date.

The GSAT-19 carries a Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of charged particles and the influence of space radiation on satellites and their electronic components.

GSAT-19 also features certain advanced spacecraft technologies including miniaturised heat pipe, fibre optic gyro, Micro Electro-Mechanical Systems (MEMS) accelerometer, Ku-band TTC transponder, as well an indigenous Lithium-ion battery.

After its separation from the GSLV MKIII in geostationary transfer orbit (GTO), GSAT-19 will use its own propulsion system to reach its geostationary orbital home.

The satellite is being termed as “a game changer communications satellite for India” as it would alone do the work of 6-7 of the older variety of communication satellites in space.

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder. It creates a communication channel between a source transmitter and a receiver at different locations on Earth.

Once the GSLV-Mk III- D1/GSAT-19 mission becomes successful, India would become self-reliant to launch four-tonne satellites on its own rocket. Earlier, the ISRO had to hire rockets from foreign space agencies to execute the operation, which cost huge amount of money.

GSLV MkIll is the next version to the presently operational launch vehicles PSLV & GSLV MkII. Satellite Launch Vehicle-3 (SLV-3) was the first launch vehicle developed indigenously by India. The successful launch of Rohini RS-1 satellite by SLV-3 on July 18, 1980 enabled India to join the select club of six countries -United States, former USSR, France, Japan, China and Britain – with the capability to launch satellites on their own. SLV-3 was followed by the Augmented Satellite Launch Vehicle (ASLV).
