What is GSLV?

The Geosynchronous Satellite Launch Vehicle (GSLV) is launch system developed by the Indian Space Research Organisation (ISRO). It was introduced to enable India to launch its INSAT-type satellites into geostationary orbit which will help India to be less dependent on foreign rockets.

What is INSAT?

The Indian National Satellite (INSAT) system is placed on the Geo-stationary orbits is presently one of the largest domestic communication satellite systems in Asia-Pacific region. It was established in 1983 starting out with INSAT-1B and initiated a major revolution in India’s communications sector.

The INSAT space segment consists of 24 satellites out of which 10 are in service.

What is Geostationary Orbit?

Geostationary Orbit is a circular orbit which is 35,786 kilometers (22,236 mi) above the Earth’s equator and following the direction of the Earth’s rotation. The objects on this orbit will have equal rotations as Earth due to which it appears to be stagnant in the sky for us. Frequently, communication satellites and weather satellites are given geostationary orbits.

When did India launch its first GSLV Vehicle and from where?

The launch of the first GSLV, called the GSLV Mk.I, took place on 18 April, 2001 from SHAR and the most recent launch was scheduled in 2010.

What is SHAR?

Satish Dhawan Space Centre (SHAR) is located at Sriharikota, Andhra Pradesh. All Indian Space Vehicles are launched from here and it gives access to space for indigenous satellites as well as commercial satellites. This space center which was previously known as SHAR (Sriharikota Range) was renamed as ‘Satish Dhawan Space Center SHAR’ on 5 September, 2002 in the fond memory of Prof. Satish Dhawan, former Chairman of the Indian Space Research Organisation(ISRO).

List of all GSLV Attempts by India

Until now, seven attempted launches have been made. India faced two successful launches and four failed ones and one was a partial failure which placed the satellite into an unplanned but a recoverable orbit.

What are the GSLV versions so far?

The first flight of GSLV Mk.I (GSLV-D1) was launched on 18 April, 2001 but the flight carrying the GSAT-1 failed to reach the correct orbit. The Space Agency made attempts to put the satellite in the correct orbit but the launch vehicle ran out of fuel.

The second GSLV was a successful attempt on 8 May, 2003 as GSAT-2 was placed on the right orbit.

On 20 September, 2004, ISRO made a third attempt and GSLV launched EDUSAT which is India’s first dedicated satellite for educational services which was also successfully placed.

On 10 July, 2006 India faced another failure after GSIV-F02 did not succeed in placing the satellite INSAT-4C into orbit.

The fifth attempt was in 2007 as ISRO released GSLV-F04 with INSAT-4CR satellite into Geosynchronous Transfer Orbit (GTO) but despondently it was added as another failure.  

India attempted two launched in 2010 but both of them failed. The first flight of GSLV Mk.II and the second one launched in December 2010 was destroyed by range safety.

Now, India is launching its eighth flight called GSLV D5 on January 5 which will be carrying GSAT-14, the communication satellite to be placed on the geostationary orbit. This launch was re-scheduled from August 19, 2013, which was cancelled after the detection of fuel leakage.

What is the main objective of GSLV mission?

The main objective of this mission is to make India less dependent on foreign rockets.

What is GSLV D5–GSAT14?

It is a 49 metre (161 ft) tall launch vehicle which can carry a weight of 415 tonnes. It is divided into three-stage vehicle which are solid, liquid and cryogenic.

 The payload attached to GSLV is about 7.8 metre (26ft) long and it prevents all the electronics and the spacecraft during its way-through the atmosphere. Once, the launch vehicle reaches an altitude of about 115 km, the payload is discarded.

It has a digital auto-pilot system which guides the vehicle to the specified orbit.

What are the benefits of GSAT 14?

GSAT 14 will enhance the broadcasting services over the GSAT-3 satellite. The satellite also carries two Ka-band beacons which is for the research purpose. It will conduct research on how weather affects Ka-band satellite communications.

The satellite is powered by two solar arrays and it produces 2,600 watts of power.
