The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and 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 in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
The Indian National Satellite System or INSAT, is a series of multipurpose geostationary satellites launched by the Indian Space Research Organisation (ISRO) to satisfy telecommunications, broadcasting, meteorology, and search and rescue operations. Commissioned in 1983, INSAT is the largest domestic communication system in the Indo-Pacific Region. It is a joint venture of the Department of Space, Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. The overall coordination and management of INSAT system rests with the Secretary-level INSAT Coordination Committee.
GSAT-3, also known as EDUSAT, was a communications satellite which was launched on 20 September 2004 by the Indian Space Research Organisation. EDUSAT is the first Indian satellite built exclusively to serve the educational sector. It is mainly intended to meet the demand for an interactive satellite-based distance education system for the country.
GSAT-1 was an experimental communications satellite launched aboard the maiden flight of the GSLV rocket. The spacecraft was equipped with instrumentation to test Pulse-code modulation (PCM) transmitting on S-band frequencies and transponders operating in the C-band. The spacecraft was unable to complete its mission after a launch failure left it in a lower than planned orbit and propulsion issues prevented the satellite from correcting this via its own maneuvering system.
Satish Dhawan Space Centre – SDSC, is the primary spaceport of the Indian Space Research Organisation (ISRO), located in Sriharikota, Andhra Pradesh.
The Liquid Propulsion Systems Centre (LPSC), Thiruvananthapuram is a research and development centre functioning under Indian Space Research Organisation (ISRO). It has two units located at Valiamala, in Thiruvananthapuram of Kerala, and Bengaluru of Karnataka. LPSC is augmented by ISRO Propulsion Complex at Mahendragiri of Tamil Nadu.
The Launch Vehicle Mark-3 or LVM3 is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). Primarily designed to launch communication satellites into geostationary orbit, it is also due to launch crewed missions under the Indian Human Spaceflight Programme. LVM3 has a higher payload capacity than its predecessor, GSLV.
GSAT-4, also known as HealthSat, was an experimental communication and navigation satellite launched in April 2010 by the Indian Space Research Organisation on the maiden flight of the Geosynchronous Satellite Launch Vehicle Mk.II rocket. It failed to reach orbit after the rocket's third stage malfunctioned. The third stage was the first Indian-built cryogenic-fuelled upper stage, and was making its first flight. The ISRO suspects that the failure was caused by the third stage not igniting.
The Vikas is a family of hypergolic liquid fuelled rocket engines conceptualized and designed by the Liquid Propulsion Systems Centre in the 1970s. The design was based on the licensed version of the Viking engine with the chemical pressurisation system. The early production Vikas engines used some imported French components which were later replaced by domestically produced equivalents. It is used in the Polar Satellite Launch Vehicle (PSLV), Geosynchronous Satellite Launch Vehicle (GSLV) and LVM3 for space launch use.
The CE-7.5 is a cryogenic rocket engine developed by the Indian Space Research Organisation to power the upper stage of its GSLV Mk-2 launch vehicle. The engine was developed as a part of the Cryogenic Upper Stage Project (CUSP). It replaced the KVD-1 (RD-56) Russian cryogenic engine that powered the upper stage of GSLV Mk-1.
GSAT-5P, or GSAT-5 Prime, was an Indian communications satellite which was lost in a launch failure in December 2010. Part of the Indian National Satellite System, it was intended to operate in geosynchronous orbit as a replacement for INSAT-3E.
GSAT-14 is an Indian communications satellite launched in January 2014. It replaced the GSAT-3 satellite, which was launched in 2004. GSAT-14 was launched by a Geosynchronous Satellite Launch Vehicle Mk.II, which incorporated an Indian-built cryogenic engine on the third stage.
PSLV-C4 was the fourth operational launch and overall seventh mission of the PSLV program. This launch was also the forty-eight launch by Indian Space Research Organisation since its first mission on 1 January 1962. The vehicle carried and injected India's first dedicated Meteorological satellite, Kalpana-1 into the Geosynchronous transfer orbit. PSLV-C4 was launched at 15:53 hours IST on 12 September 2002 from Satish Dhawan Space Centre.
GSAT-6A was a communication satellite launched by the Indian Space Research Organisation (ISRO) It featured a 6-metre (20 ft) unfurlable S-band antenna similar to the one used on GSAT-6. Around 17 minutes after lift-off, the three stage GSLV Mk.II rocket flying on GSLV F08 mission successfully injected the satellite into a geosynchronous transfer orbit. Due to power failure during its orbit raising burns the communication was lost with GSAT-6A before it could reach its final circular geostationary orbit (GSO).
GSAT-29 is a high-throughput communication satellite developed by the Indian Space Research Organisation (ISRO). The mission aims at providing high-speed bandwidth to Village Resource Centres (VRC) in rural areas. The two Ku and Ka operational payloads will provide communication services to Jammu and Kashmir and Northeast India under Digital India programme. At the time of launch GSAT-29 was the heaviest satellite, weighing 3,423 kg (7,546 lb), that was placed in orbit by an Indian launch vehicle. Approved cost of GSAT-29 is ₹175.63 crore (US$21 million).
The S139 is a Solid Rocket Booster manufactured by the Indian Space Research Organisation at the Satish Dhawan Space Centre in the SPROB facility. The rocket motor was first developed for use in the Polar Satellite Launch Vehicle. Later it was utilised in the GSLV MKII. It uses hydroxyl-terminated polybutadiene (HTPB) as a propellant. It has a maximum thrust of 4800 kN.
The GSLV F12 is the 15th flight of the GSLV and the 9th flight of Mk2 variant using indigenous Cryogenic engine.
The Next Generation Launch Vehicle or NGLV or "Soorya" is a three-stage partially reusable Heavy-lift launch vehicle, currently under development by the Indian Space Research Organisation (ISRO). This vehicle is designed to replace currently operational systems like PSLV, GSLV and LVM3.
