Cabinet approves Continuation Programme for GSLV Mk-III with Chandrayaan -2 mission in April, rover will spend 14 active days on moon’s surface

The Union Cabinet chaired by PM Narendra Modi has approved funding for the for Geosynchronous Satellite Launch Vehicle Mark-III (GSLV Mk-III) continuation programme (Phase-I) consisting of ten (10) GSLV (Mk-III) flights, at a total estimated cost of Rs. 4338.20 crores. This includes Rs. 4338.20 Crores and includes the cost of ten GSLV Mk-III vehicles, essential facility augmentation, Programme Management and Launch Campaign.

The GSLV Mk-III continuation Programme – Phase 1 is the first phase of operational flights that will enable the launch of 4 tonne class of communication satellites to meet the country’s satellite communication requirements.

The operationalisation of GSLV Mk-III will make the country self-reliant in the launching capability of 4 tonne class of communication satellites, and sustain & strengthen the space infrastructure and reduce the dependence on procured launches from foreign countries.

The GSLV Mk-III Continuation Programme – Phase 1 will meet the launch requirement of communication satellites to meet the national demand for High Throughput Satellites for rural broadband connectivity, increase and sustain the availability of transponders for DTH, VSAT and Television broadcasters.

GSLV Mk-III Continuation Programme – Phase 1 will be the first phase of operational flights of the GSLV Mk-III launch vehicle and the approval will cater to the launch of satellite missions during the period 2019-2024.

The Geosynchronous Satellite Launch Vehicle Mark-III (GSLV Mk-III) has been developed towards achieving indigenous launch capability to launch 4 tonne class of satellites into Geosynchronous Transfer Orbit (GTO). It has completed one experimental flight (LVM3-X) in 2014 and one developmental flight (GSLV MkIII-D1) in 2017. The second developmental flight will be completed by Q2 of 2018-19 this year. The Continuation Programme – Phase 1 will enable independent access to space for 4 tonne class of communication satellites, and establish GSLV Mk-III as a cost-effective workhorse vehicle to launch 4 tonne class of communication satellites in order to meet the national requirements as well as to boost its commercial potential in the international market for launch services.

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.

The first developmental flight of GSLV Mk III, the GSLV-Mk III-D1 successfully placed GSAT-19 satellite to a Geosynchronous Transfer Orbit (GTO) on June 05, 2017 from SDSC SHAR, Sriharikota.
