Nellore: Isro is preparing to launch GSAT-6 communications satellite aboard the Geo-synchronous Satellite Launch Vehicle (GSLV) D6 from the Satish Dhawan Space Centre at Sriharikota on Thursday. Nineteen months after it successfully flight-tested India’s first home-made cryogenic engine, Isro is ready for a keenly-awaited encore.


The desi cryogenic engine will now power the upper stage of the GSLV-D6, which will put the 2140 kg GSAT-6 in orbit. This is the ninth flight in the series and fifth developmental flight. The present flight-test of the engine is aimed at validating ISRO’s prowess in the complex cryogenic technology.


Its success is also critical to prove that the cryo engine is ready for ISRO’s commercial missions. GSAT-6 will provide S-band communication services in the country. After reaching GTO, the satellite will use its own propulsion system to reach its final geostationary orbital home.


The vehicle is configured with all three stages including the CUS similar to the ones successfully flown during the previous GSLV-D5 mission that placed GSAT-14 satellite carried on-board in the intended GTO with high precision. The smooth metallic structure of GSLV-D6 has a diameter of 3.4 m. The overall length is 49.1 m with a lift-off mass of 416 tonnes.
