Nellore, May 1: The Indian Space Research Organisation (ISRO) have achieved several milestones within few years such as the launch of 104 satellites in one go, Remote Sensing Satellite PSLV-C36/ResourcesAT-2A, remote sensing satellite RESOURCESAT-2A, Cryogenic Upper Stage engine for GSLV Mark III etc. Now, after the Polar Satellite Launch Vehicle (PSLV) has established, ISRO is set to launch India's Geosynchronous Satellite Launch Vehicle (GSLV-F09) on Friday this week, i.e on 5 May 2017.

Notably, the GSLV-F09 will carry the communication satellite GSAT-9 and it would be launched from the Second Launch Pad at Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh. The GSAT-9 communication satellite is being launched with an objective to provide different communication applications in Ku-band with coverage over South Asian countries.

Importantly, this satellite weighs over 2,230 kg and took three years to build at a huge cost of Rs 235 crore. However, operational costs and insurance are expected to take the total cost to Rs 450 crore. The satellite will enable a full range of applications and services in the areas of telecommunications and broadcasting, tele-education, telemedicine and disaster management support. The satellite has a mission life of 12 years.

ISRO said, "GSAT-9 is configured around the ISRO's standard I-2K bus, with a lift-off mass of 2,230 kg. The main structure of the satellite is cuboid in shape built around a central cylinder with a mission life of more than 12 years."

Earlier, in the month of February this year, ISRO successfully ground tested its indigenously developed Cryogenic Upper Stage engine for GSLV Mark III at its Liquid Propulsion Complex.

Background:

The Geosynchronous Satellite Launch Vehicle was primarily developed to launch INSAT class of satellites into Geosynchronous Transfer Orbits. GSLV is being used for launching GSAT series of satellites. GSLV is a three-stage launcher that uses one solid rocket motor stage, one Earth-storable liquid stage and one cryogenic stage.

The most recent flight of GSLV, the GSLV-D5, placed GSAT-14 into its planned orbit and marked the first successful flight of the indigenous cryogenic stage. Earlier, GSLV had launched various communication satellites among which EDUSAT is notable, being India's first satellite built exclusively to serve the educational sector through satellite based distance education.
