Geosynchronous Satellite Launch Vehicle

GSLV stands for Geosynchronous Satellite Launch Vehicle. It's the satellite-launch vehicle developed and operated by the Indian Space Research Organisation ( ISRO ).
It's used to launch satellites and space objects into the Geosynchronous Transfer Orbits.
It's launched eleven satellites till date (July 2017).
The primary satellite was launched in 2001 and therefore the most recent satellite was launched on 5 May 2017.

GSLV Description

GSLV is 49 meters tall. It's a three-stage launcher with a lift-off mass of 414.75 tonnes.
It's provided strap-on motors. The present configuration of GSLV can put a payload of around 2500 kg within the Geostationary Transfer Orbit (GTO).
It can put a payload up to five tonnes in Low Earth Orbits (LEO).

In this stage, S-138 solid rocket motor given four liquid engine strap-on motors is used to get thrust. It can generate a maximum thrust of 4700 Kilo Newton.

This stage uses a liquid rocket called Vikas. A maximum thrust of 800 Kilo Newton is generated during this stage.

During this stage, a cryogenic engine is used. This engine uses liquefied hydrogen and oxygen as fuel. The CE=7.5 is that the first cryogenic engine of India.

The GSLV project was initiated in 1990 to become an independent nation in launching geosynchronous satellites.
On 18 April 2001, the primary developmental flight of GSLV Mk I (GSLV-D1) was launched on 18 April 2001. It had been unable to succeed in the correct orbit.
It became operational after it successfully placed GSAT-2 in its second developmental flight.
In September 2004, it launched EDUSAT the first satellite of India for educational services.
The second operational flight (GSLV FO2) wasn't ready to place satellite (INSAT-4C) into the orbit.
The first successful flight of GSLV Mark. II was the launch of GSLV-F05 on 5 January 2014 using an indigenously developed cryogenic engine (CE-7.5.)
On 8 September 2016, GSLV-F05 was launched to launch the INSAT-3DR satellite from Sriharikota.
On 5 May 2017, GSLV-F09 successfully launched GSAT-9 from Satish Dhawan Space Center, Sriharikota.
