Indian Space Research Organisation (ISRO) has successfully ground tested its indigenously developed Cryogenic Upper Stage engine for GSLV Mark III at its Liquid Propulsion Complex at Mahendragiri in Tirunelveli district of Tamil Nadu.
ISRO Chairman AS Kiran Kumar said the full duration flight test of cryogenic upper stage for GSLV Mark III was successful. He said test was last in the series before going for an actual rocket launch. The engine will be put into use in April.
The C25 stage is the most powerful upper stage developed by ISRO and uses Liquid Oxygen and Liquid Hydrogen propellant combination. The development of C25 cryogenic stage will provide ISRO capability to launch four ton class satellites in Geosynchronous Transfer Orbit
GSLV-Mk III-D1 / GSAT-19
GSAT-19 is planned as the payload for the first developmental flight of the indigenous GSLV-Mk III-D1 Launcher. The satellite is planned to carry Ka 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 experiments in Electrical propulsion System, indigenous Li ion battery, indigenous Bus bars for power distribution, etc.
