GSLV Mk III-D1/GSAT-19 Mission to be launched on June 05, 2017 from SDSC SHAR, Sriharikota

Bangalore: Indian scientists are preparing to launch GSLV Mk III which is capable of carrying two times more weight into space than its predecessors. “We are pushing ourselves to the limits to ensure that this new fully self-reliant Indian rocket succeeds in its maiden launch,” said ISRO chairman AS Kiran Kumar. GSLV Mk-III will enable India to send manned missions to space.
GSLV-Mk III is capable of launching 4 ton class of satellites to Geosynchronous Transfer orbit (GTO). It is a three-stage vehicle with two solid motor strap-ons (S200), a liquid propellant core stage (L110) and a cryogenic stage (C25).
GSLV-Mk III-D1 is the first developmental flight, carrying 3136 kg GSAT-19 satellite to a Geosynchronous Transfer Orbit (GTO). The vehicle is configured with a 5 m ogive payload fairing and slanted strap-on nose cone to provide aerodynamic robustness.
GSAT-19 satellite with a lift-off mass of 3136 kg, is the communication satellite of India, configured around the ISRO’s standard I-3K bus.
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.
About the Launch Vehicle
GSLV Mk III is a three-stage heavy lift launch vehicle developed by ISRO. The vehicle has two solid strap-ons, a core liquid booster and a cryogenic upper stage.
GSLV Mk III is designed to carry 4 ton class of satellites into Geosynchronous Transfer Orbit (GTO) or about 10 tons to Low Earth Orbit (LEO), which is about twice the capability of GSLV Mk II.
The two strap-on motors of GSLV Mk III are located on either side of its core liquid booster. Designated as ‘S200’, each carries 205 tons of composite solid propellant and their ignition results in vehicle lift -off . S200s function for 140 seconds. During strap-ons functioning phase, the two clustered Vikas liquid Engines of L110 liquid core booster will ignite 114 sec after lift -off to further augment the thrust of the vehicle. These two engines continue to function after the separation of the strap-ons at about 140 seconds after lift -off.
The first experimental flight of LVM3, the LVM3-X/CARE mission lifted off from Sriharikota on December 18, 2014 and successfully tested the atmospheric phase of flight. Crew module Atmospheric Reentry Experiment was also carried out in this flight. The module reentered, deployed its parachutes as planned and splashed down in the Bay of Bengal.
GSLV-Mk III-D1 is the first developmental flight, carrying 3136 kg GSAT-19 satellite to a Geosynchronous Transfer Orbit (GTO).
