ISRO to launch GSAT-19 using its heaviest rocket, the GSLV-MK III on 5 June at 5.28 pm

The GSLV-MK III-D1 is a three-stage vehicle with two solid motor strap-ons, a liquid propellant core stage and a cryogenic stage.


India will be launching, on June 5, communication satellite GSAT-19 using its heaviest rocket which has a capacity to lift a four ton satellites to geosynchronous transfer orbit (GTO), the Indian space agency said on Tuesday. According to Indian Space Research Organisation (ISRO), the geosynchronous satellite launch vehicle - Mark III (GSLV-Mk III) is scheduled to be launched on June 5 at 5.28 p.m.

The rocket in its first developmental flight, will carry communication satellite GSAT-19 weighing 3,136 kg as it blasts off from the second launch pad at the rocket port in Sriharikota in Andhra Pradesh. The GSLV-MK III-D1 is a three-stage vehicle with two solid motor strap-ons, a liquid propellant core stage and a cryogenic stage (C25). The notable aspect of this rocket is that the main and bigger cryogenic engine has been developed by space scientists here and will be powering the rocket for the first time. GSAT-19 carries Ka/Ku-band high throughput communication transponders.

Besides, it 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.

The GSLV-MK III, given the nick name "fat boy", is going to play a major role in the future of the Indian Space Program. The rocket, or a variant is the most likely candidate to be used for any future ISRO manned missions to space. The GSAT-19 on board has the capacity of four conventional satellites launched by India so far. It is the first in a series of communication satellites with increasing capacity, being launched to meet the future communication requirements of the country. The GSAT-19, the GSAT-11 and the GSAT-20 will together boost the broadband capacity and revolutionise the entertainment industry.
