. SHAR was named as 'Satish Dhawan Space Centre SHAR' (SDSC), on 5 September 2002, in memory of Prof Satish Dhawan, former Chairman of the ISRO.

SHAR covers a total area of about 145 square kilometre with a coastal length of 27 km (16.8 mi). Prior to its acquisition for ISRO by the Indian Government, its was a firewood plantation of Eucalyptus and Casuarina trees. This island is affected by both south-westerly and north-easterly monsoons, but heavy rains come only in October and November. Thus many clear days are available for out-door static tests and launchings.

Launch History

Originally known as the Sriharikota Range (SHAR) and later named after Satish Dhawan

, it is India's primary orbital launch site to this day. The first flight-test of 'Rohini-125', a small sounding rocket which took place on October 9, 1971 was the first ever spaceflight from SHAR. Since then technical, logistic and administrative infrastructure have been enhanced. Together with the northerly Balasore Rocket Launching Station, the facilities are operated under the ISRO Range Complex (IREX) headquartered at SHAR.

Satellite Launch Vehicle (SLV)

 125 sounding rockets were launched on 9 and 10 October 1971. Previously, India used Thumba Equatorial Rocket Launching Station

 (TERLS), on the west coast of India, to launch sounding rockets. The first test launch of the complete SLV-3 rocket occurred in August 1979 but it was only partially successful following a malfunction in the second stage guidance system. SHAR facilities worked satisfactorily during the SLV-3 preparation and launch. On 18 July 1980 the SLV-3 successfully launched India's third satellite. Out of the four SLV launches from SHAR, two were successful.

Augmented Satellite Launch Vehicle (ASLV)

The ASLV

 orbital launcher was integrated vertically, beginning with motor and subassembly preparations in the Vehicle Integration Building (VIB) and completed on the pad within the 40 m tall Mobile Service Structure. The first ASLV launch from SHAR took place in 1987 and resulted in a failure. Eventually, out the four ASLV launches from 1987–94, only one was successful.

Polar Satellite Launch Vehicle (PSLV)

The PSLV launch complex was commissioned during 1990. It has a 3,000 tonne, 76.5 m high Mobile Service Tower (MST) which provides the SP-3 payload clean room. The solid propellant motors for the PSLV are processed by SHAR, which also carries out launch operations. The first launch of the PSLV took place on 20 September 1993. Since then out of 15 launches, PSLV has a recorded 14 successes. PSLV is launched both from the first and the second launch pad.

Facilities

The Centre has two operational orbital launch pads. SHAR is ISRO's satellite launching base and additionally provides launch facilities for the full range of Rohini sounding rockets
Rohini sounding rocket series

. The Vehicle Assembly, Static Test and Evaluation Complex (VAST, previously STEX) and the Solid Propellant Space Booster Plant (SPROB) are located at SHAR for casting and testing solid motors. The site also has a Telemetry Tracking & Control centre, the Management Service Group and Sriharikota Common Facilities. The PSLV launch complex was commissioned in 1990. It has a 3,000 tonne, 76.5 m high Mobile Service Tower (MST) which provides the SP-3 payload clean room.

The solid propellant space booster plant(SPROB) processes large size propellant grains for the satellite launch vehicles. The Static Test & Evaluation Complex (STEX) tests and qualifies different types of solid motor for launch vehicles. The closed center at SHAR houses computers and data processing, closed circuit television, real-time tracking systems and meteorological observation equipment. It is linked to three radars located at Sriharikota and the five stations of ISRO's Telemetry, Tracking & Command Network (ISTRAC

).

The propellant production plant produces composite solid propellant for rocket motors of ISRO using ammonium perchlorate (oxidiser), fine aluminium powder (fuel) and hydroxyl terminated polybutadiene (binder). The solid motors processed here include those for the first stage booster motor of the Polar Satellite Launch Vehicle (PSLV) — a five segmented motor of 2.8 m diameter and 22 m length, weighing 160 tons with a thrust level of 450 tons.

Rocket motors and their subsystems have to be rigorously tested and evaluated on ground before they are declared flight worthy. The facilities at SDSC SHAR are used for testing solid rocket motors, both at ambient conditions and simulated high altitude conditions. Besides these, there are facilities for conducting Vibration, Shock, Constant Acceleration and Thermal/humidity tests.

SDSC SHAR has infrastructure for launching satellites into low earth orbit, polar orbit and geo-stationary transfer orbit. The launch complexes provide support for vehicle assembly, fuelling, checkout and launch operations. The Centre also has facilities for launching sounding rockets for atmospheric studies. The mobile service tower, launch pad, preparation facilities for different launch stages & spacecraft, storage, transfer and servicing facilities for liquid propellants, etc., are the principal parts of the PSLV/GSLV launch complex.

 programme additional facilities are being set up at SDSC. A new plant is being set up to process heavier class boosters with 200 tonnes of Solid propellant. The static test complex is being augmented for qualifying the S-200 booster. Other new facilities include a Solid Stage Assembly Building, Satellite Preparation and Filling Facility and Hardware Storage buildings. The existing liquid propellant and cryogenic propellant storage and filling systems, Propellant Servicing Facilities will also be augmented. The range instrumentation system will be enhanced further.

Old Launch Pad (Launch Pad-1)

This was the first launch pad built at SHAR during the late 1960s. It became operational in 1971 and since then numerous launches have taken place. It is operational even today and is used for PSLV launches.

Second Launch Pad (SLP)

The SLP at SHAR is a state-of-the-art launch complex. SLP is configured as a universal launch pad capable of accommodating all the launch vehicles of ISRO including the advanced launch vehicles to be built in the next decade and beyond. It became operational in 2005.

Third Launch Pad

The Third Launch Pad is specifically being built for manned missions at a cost of Rs 600 crores. It is scheduled to be completed by 2012 and the first test flight would take place in 2013.
