GSLV satellites from 2001 to 2014

1. GSLV (Geosynchronous Satellite Launch Vehicle)

2. Geosynchronous Satellite Launch Vehicle  (abbreviated as  GSLV ) is an  expendable launch system  operated by the  Indian Space Research Organisation (ISRO)  It was developed to enable  India  to launch its satellites indigenously without dependence on foreign aid. GSLV has attempted eight launches to date, since its first launch in 2001 through its most recent launch in 2014

3. history The Geosynchronous Satellite Launch Vehicle (GSLV) project was initiated in 1990 with the objective of acquiring an  Indian  government launch capability for Geosynchronous satellites India has depended on the United States and Europe for the launch of INSAT class of satellites. [3] GSLV uses major components that are already proven in the  Polar Satellite Launch Vehicle (PSLV)  launchers in the form of the S125/S139 solid booster and the liquid-fueled  Vikas engine

5. Vehicle description The 49 metres (161 ft) tall GSLV, with a lift-off mass of 415 tonnes (457 tons), is a three-stage vehicle with solid, liquid and cryogenic stages respectively The payload fairing, which is 7.8 metres (26 ft) long and 3.4 metres (11 ft) in diameter, protects the vehicle electronics and the spacecraft during its ascent through the atmosphere

6. Launch history  All GSLV launches have been conducted from the  Satish Dhawan Space Centre  in  Sriharikota .

7. GSLV-D1

8. GSLV-D1 The first developmental flight of Geo-synchronous Satellite Launch Vehicle, GSLV-D1, was successfully carried out on April 18, 2001 from SHAR Centre, Sriharikota Payload mass is 1,540 kg  ISRO claims the launch to be successful and claims GSLV-D1 as failure

9. Features of gslv d-1 The GSLV-D1 boasts of several unique features. For the first time, a cryogenic engine has been used on an ISRO vehicle. Second, the 1,540-kg satellite (GSAT-1) is the heaviest satellite to be carried by an Indian-made satellite launch vehicle. The GSLV-D 1 is to be followed by two more developmental launches (GSLV-D2 and GSLV-D3), which will progressively test with increased payloads.

10. Gslv d-2

11. Gslv d-2 GSLV-D2 is the second developmental test flight of the vehicle. Successfully launched on 8 th May 2003 from SHAR Centre, Sriharikota Payload mass is 1,825 kg ISRO claims GSLV D-2 as Successful mission

12. Features of gslv d-2 The GSLV-D2 features several improvements over the GSLV-D1, which was sent up into the space in April 2001. Importantly, the rocket launched today carried a heavier satellite-which weighed 1,800 kg, as compared to the 1,540 kg of GSLV-D1. In order to be able to carry a heavier payload, the rocket carried more fuel and the fuel was fired at a higher pressure. These were the parameters that today's mission wanted to put to test, and the result was a complete success

13. GSLV-F01

14. GSLV-F01 GSLV-F01 is the third flight of ISRO’s Geosynchronous Satellite Launch Vehicle and this is the first operational flight launched in 20 th September 2004 from SHAR Centre, Sriharikota . Payload mass is 1,950 kg ISRO claims GSLV-F01 as a Successful mission

15. Feastures of gslv-f01 The Aluminum alloy GSLV payload fairing is 3.4 m in diameter and is 7.8 m long. GSLV employs various separation systems such as Flexible Linear Shaped Charge (FLSC) for the first stage, pyro actuated collet release mechanism for second stage and Merman band bolt cutter separation mechanism for the third stage. Spacecraft separation is by spring thrusters mounted at the separation interface. The three-axis attitude stabilisation of GSLV is achieved by autonomous control systems provided in each stage. Single plane Engine Gimbal Control (EGC) of the four strap- ons of the first stage are used for pitch, yaw and roll control.

16. Gslv-f02

17. Gslv-f02 GSLV-F02 launched INSAT-4C on July 10, 2006  from SHAR Centre, Sriharikota . Payload mass is 2,168 kg Both rocket and satellite had to be destroyed over the Bay of Bengal after the  rocket's trajectory veered  outside of permitted limits

19. Gslv-f04

20. Gslv-f04 GSLV-F04 is the fifth flight of India's Geosynchronous Satellite launch Vehicle (GSLV) launched in 2 nd September 2007 in SHAR Centre, Sriharikota . Payload mass is 2,160 kg ISRO claims the mission to be Partially failure

21. Features of gslv-fo4 The 49 m tall GSLV, with a lift-off mass of 415 tonne , is a three-stage vehicle with solid, liquid and cryogenic stages. The first stage of GSLV, one of the largest in the world, uses Hydroxyl Terminated Polybutadiene (HTPB) based propellant. The second stage and the four strap-on motors surrounding the first stage use liquid propellant ' Vikas ' engine burning UH25 and Nitrogen Tetraoxide . The third stage is a cryogenic stage using liquid Hydrogen as fuel and liquid Oxygen as oxidiser .

22. Gslv-d3

23. Gslv-d3 The GSLV-D3 was the sixth flight of ISRO's Geosynchronous Satellite Launch Vehicle (GSLV) as well as its third developmental flight. Launched in 15 April 2010 from SHAR Centre, Sriharikota . Payload mass is 2,220 kg ISRO claims the mission to be unsuccessful

24. Features of Gslv-d3 First flight test of the ISRO designed and built Cryogenic Upper Stage. Failed to reach orbit due to malfunction of Fuel Booster Turbo Pump (FBTP) of the Cryogenic Upper Stage

25. GSlv-f06

26. Gslv-f06 GSLV-F06 was the seventh mission of Geosynchronous Satellite Launch Vehicle (GSLV) launched in 25 th December 2010 from SHAR Centre, Sriharikota . Payload mass is 2,130 kg Destroyed by range safety officer after loss of control of liquid-fueled boosters

27. Features of gslv-f06 The major changes incorporated in compared to the previous flight include loading of 15 tonnes of propellants in its third stage and the uprating of the third stage thrust by 26%. Besides, the overall length of the vehicle was increased by about 1.3 metres.Hence the mission was unsuccessful.

28. Gslv-d5

29. Gslv-d5 GSLV-D5 is the eighth flight of India's Geosynchronous Satellite Launch Vehicle (GSLV). It is also the fourth developmental flight of GSLV Payload mass is 1,980 kg This was the first successful flight of the cryogenic stage which was developed indigenously in India

30. Features of gslv-d5 Second flight of GSLV with indigenous cryogenic upper stage(CUS) developed by ISRO’s Liquid Propulsion Systems Centre (LPSC) was launched successfully on 5 January 2014. It was a launch with precision of 40 metres (130 ft). All three stages of launch were carried out successfully
