The Indian Space Research Organisation will launch GSLV Mark III-D1 with a payload of four tonnes on June 5.
At present, ISRO has the capability to launch payloads of up to 2.2 tonnes and anything above that it had to tap Ariane or other launch facilities.
GSLV-Mk III is the next generation launch vehicle of ISRO 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 GSAT-19 satellite.
GSAT-19 is the payload for the indigenous GSLV-Mk III-D1 Launcher. The satellite will carry Ka-band and Ku-band payload along with a Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of the charged particles and influence of space radiation on spacecraft and electronic components. GSAT-19 satellite will employ advanced spacecraft technologies including bus subsystem, indigenous Li ion battery, indigenous Bus bars for power distribution, etc.
The Geosynchronous Satellite Launch Vehicle Mark III is a gamechanger capable of launching 4-tonne category of satellites from Sriharikota. It packs an Indian cryogenic third stage and higher payload as against the current GSLV.
Apart from deploying advanced spacecraft technologies, the satellite would carry ka and ku-band payload along with a Geostationary Radiation Spectrometer that will help research space radiation.
ISRO will soon launch an innovative Outreach centre in Hyderabad, which would serve as a hub/centre for research, and base for start-ups and entrepreneurs to explore new business opportunities.
