GSLV LAUNCHING


GSLV Launching gallery show the sequence of Events that will takes place at the time of Launching. GSLV (Geosynchronous Satellite Launch Vehicle ) has been launched from Second Launch Pad at Satish Dhawan Space center - SHAR.

ISRO’s Geosynchronous Satellite Launch Vehicle (GSLV), in its first operational flight (GSLV-F01) launched EDUSAT, India’s first exclusive satellite for educational services from Satish Dhawan Space Centre SHAR, Sriharikota.

GSLV was declared operational (GSLV-MK I) after both its developmental test flights conducted in April 2001 and May 2003 were successful. In its first operational flight, GSLV-F01, successfully launched the 1,950 kg EDUSAT on September 20, 2004.

PSLV-C7 Successfully Launched

ISRO’s Polar Satellite Launch Vehicle, PSLV-C7, successfully launched four satellites -- India’s CARTOSAT-2 and Space capsule Recovery Experiment (SRE-1), Indonesia’s LAPAN-TUBSAT and Argentina’s PEHUENSAT-1 into a 635 km high polar orbit. For the first time, a Dual Launch Adopter (DLA) was used in PSLV to accommodate two primary satellites in tandem.

After the final count down, PSLV-C7 lifted off from the first launch pad at SDSC SHAR, at 9.23 am with the ignition of the core first stage and four of the six strap-on motors.

The four satellites have been placed in a polar orbit at an altitude of 637 km with an inclination of 97.9 deg with respect to the equator.

Geosynchronous Satellite Launch Vehicle

The GSLV or Geosynchronous Satellite Launch Vehicle was developed by Indian Space Research Organization (ISRO) to launch INSAT-type satellites into geostationary orbit to make India less dependent on foreign rockets. The GSLV improved on the performance of the PSLV with the addition of liquid strap-on boosters and a cryogenic upper stage.

It is a three-stage launch vehicle with the first stage being solid-propelled, the second liquid-propelled and the final stage being cryogenically propelled. The solid first and liquid second stages are carried over from the PSLV. The GSLV used cryogenic upper stage supplied by Russia, having ordered 7 upper stages. India originally tried to buy the technology to build a cryogenic upper stage from Russia, but under pressure from the United States, that technology was not provided. Therefore, ISRO has been working on developing a cryogenic upper stage for the past eleven years.

A geostationary orbit (GEO) is a geosynchronous orbit directly above the Earth's equator (0º latitude). From the ground, a geostationary object appears motionless in the sky and is therefore the orbit of most interest to operators of artificial satellites (including communication and television satellites). Due to the constant 0° latitude, satellite locations may differ by longitude only.

Polar Satellite Launch Vehicle

The PSLV or Polar Satellite Launch Vehicle is an expendable launch system operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun synchronous orbits, a service that was, until the advent of the PSLV,commercially viable only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO).

A sun-synchronous orbit (also rarely called a heliosynchronous orbit) is a geocentric orbit which combines altitude and inclination in such a way that an object on that orbit passes over any given point of the Earth's surface at the same local solar time. The surface illumination angle will be nearly the same every time. This consistent lighting is a useful characteristic for satellites that image the earth's surface in visible or infrared wavelengths (e.g. weather, spy and remote sensing satellites). There is, of course, a yearly oscillation of the actual solar time of passage because of the eccentricity of the Earth's orbit.

Sriharikota (SHAR)

The Sriharikota Launching Range is developed into the most important center, with test, assembly and launch facilities for large multi-stage rockets and satellite launchers, and tracking, telemetry and tele-command stations for Indian spacecraft।It is situated in the Sriharikota Island, on India's east coast, about 62 miles (100kMadm) north of Madras at 13°47' North and 80°15' East.Sriharikota, is an island in the Nellore District of Andhra Pradesh State, lies along the east of Pulicat Lake and is reached by road from Madras.

SHAR covers a total area of about 56 sq miles (145 sqkm) with a coastal length of 167 miles (27km). The range became operational when three Rohini 125 sounding rockets were launched on 9 and 10 October 1971. Since then, the ISRO facilities at SHAR have expanded. The solid propellant space booster plant 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.

Indian space Research Organization

The Indian Space Research Organisation (ISRO) is India's national space agency. With its headquarters in Bangalore, the ISRO employs approximately 20,000 people, with a budget around 815 million USD at current exchange rates. Its mandate is the development of technologies related to space and their application to India's development. The current Chairman of ISRO is G. Madhavan Nair. In addition to domestic payloads, it offers international launch services.

The Department of Space (DOS) has, over the years, built up a strong research and development and technology base with necessary infrastructure and manpower for implementing the space programme.

The various space centres of DOS are as follows:
Vikram Sarabhai Space Centre (VSSC)
ISRO Satellite Centre (ISAC)
Satish Dhawan Space Centre, SHAR
Liquid Propulsion Systems Centre (LPSC)
Space Applications Centre (SAC)
Development and Educational Communication Unit (DECU)
ISRO Telemetry, Tracking and Command Network (ISTRAC)
INSAT Master Control Facility (MCF)
ISRO Inertial Systems Unit (IISU)
