The Indian National Satellite System or INSAT, is a series of multipurpose geostationary satellites launched by 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.
AsiaStar is an American communications satellite which was operated by 1worldspace. It was constructed by Matra Marconi Space with Alcatel Space based on the Eurostar E2000+ bus design. Launch occurred on 21 March 2000, at 23:29:00 UTC. The launch was contracted by Arianespace, and used an Ariane 5G carrier rocket flying from ELA-3 at the Centre Spatial Guyanais. The INSAT-3B satellite was launched on the same rocket.
JCSAT-11, was a geostationary communications satellite ordered by JSAT Corporation which was designed and manufactured by Lockheed Martin on the A2100 platform. The satellite was designated to be used as an on-orbit, but was lost on launch failure.
The Master Control Facility (MCF) is a facility set up by the Indian Space Research Organisation (ISRO) in the city of Hassan in the Indian state of Karnataka. Established in 1982, this facility is responsible for monitoring and controlling geostationary and geosynchronous satellites launched by ISRO. This was the only Master Control Facility of ISRO till another one was established in Bhopal in 2005.
Arabsat-1B was a Saudi Arabian communications satellite which was operated by Arabsat. It was used to provide communication services to the Arab States. It was constructed by Aérospatiale, based on the Spacebus 100 satellite bus, and carried two NATO E/F-band and twenty five NATO G/H-Band transponders. At launch, it had a mass of 1,270 kilograms (2,800 lb), and an expected operational lifespan of seven years.
INSAT-2DT, previously Arabsat-1C and also known as INSAT-2R, was a Saudi Arabian and subsequently Indian communications satellite which was operated initially by Arabsat, and then by the Indian National Satellite System.
INSAT-1B was an Indian communications satellite which formed part of the Indian National Satellite System. Launched in 1983, it was operated in geostationary orbit at a longitude of 74 degrees east. At the end of its seven-year design life it was replaced by the newly launched INSAT-1D, dropping to backup status. In 1992, it was relocated to 93° east, before being decommissioned in August 1993.
INSAT-2E is an Indian geostationary communications and weather satellite which is operated by the Indian National Satellite System. It is positioned in geostationary orbit at a longitude of 83° East, from where it is used to provide communications services to Asia and Australia. It also carries two meteorological instruments; the Very High Resolution Radiometer, and a CCD camera capable of returning images with a resolution of one kilometre.
INSAT 3E is a defunct communication satellite built by Indian Space Research Organisation. It was launched on September 28, 2003, from the European Space Agency's spaceport in French Guiana on board the Ariane rocket. The satellite had a launch mass of 2750 kilograms. It is the 4th satellite launched in the INSAT-3 series for INSAT. It was designed for providing high-speed communication, Television, VSAT & Tele-education services and was an important landmark in Indian Space Programme.
INSAT-3A, a multipurpose satellite built by ISRO was launched by Ariane in April 2003. It is located at 93.5 degree East longitude. It is third satellite in INSAT-3 series after INSAT-3B & INSAT-3C. Built at a cost of $53 mn, it provides communication, weather, and search and rescue services.
INSAT-3C is a multipurpose satellite built by ISRO and launched by Arianespace in Jan 2002. INSAT-3C is the second satellite of the INSAT-3 series. All the transponders provide coverage over India. Insat-3C is controlled from the Master Control Facility at Hassan in Karnataka. It will provide voice, video and digital data services to India and neighboring countries.
INSAT-4CR was a communications satellite operated by ISRO as part of the Indian National Satellite System. Launched in September 2007, it replaced the INSAT-4C satellite which had been lost in a launch failure the previous year. The satellite was initially stationed in geostationary orbit at a longitude of 74 degrees east, with expected operational life of at least ten years, however this may have been reduced by the underperformance of the Geosynchronous Satellite Launch Vehicle which placed it into orbit. INSAT-4CR is planned to be replaced by GSAT-31, which was launched on February 6, 2019.
GSAT-10 is an Indian communication satellite which was launched by Ariane-5ECA carrier rocket in September 2012. It has 12 KU Band, 12 C Band and 6 lower extended c band transponders, and included a navigation payload to augment GAGAN capacity. Following its launch and on-orbit testing, it was placed in Geosynchronous orbit at 83.0° East, from where it will provide communication services in India.
INSAT-4E, also known as GSAT-6, is a member of the INSAT family and is a multimedia communication satellite that will offer a Satellite Digital Multimedia Broadcasting (S-DMB) service across several digital multimedia terminals or consoles which can be used to provide information services to vehicles on the fly and to the mobile phones. The satellite can be used for other social and strategic applications.
INSAT-1A was an Indian communications satellite which formed part of the Indian National Satellite System. Launched in 1982, it was operated in geostationary orbit at a longitude of 74° east. Following a series of failures, the satellite was abandoned in September 1982, less than six months into a seven-year mission.
INSAT-4B was an Indian communications satellite which forms part of the Indian National Satellite System. Launched in 2007, it was placed in geostationary orbit at a longitude of 93.48° East.
JCSAT-3A, known as JCSAT-10 before launch, is a geostationary communications satellite operated by SKY Perfect JSAT Group (JSAT) which was designed and manufactured by Lockheed Martin on the A2100 platform.
Intelsat IV F-7 was a geostationary communication satellite built by Hughes, it was owned by Intelsat. The satellite was based on the HS-312 platform and its estimated useful life was seven years.
Intelsat 706 is a geostationary communication satellite that was built by Space Systems/Loral (SSL). It is located in the orbital position of 157 degrees east longitude and it is currently in an inclined orbit. The same is owned by Intelsat. The satellite was based on the LS-1300 platform and its estimated useful life was 15 years.
INSAT-2D was an Indian communications satellite. Launched on 4 June 1997, and similar to INSAT-2C, INSAT-2D went out of order on October 4, 1997, because of a power inconsistency problem and was later replaced by INSAT-2DT, an in-orbit satellite which was previously known as ARABSAT-1C. The main aim of the satellite was improved communication. In the INSAT-2 series, INSAT-2D was the fourth consecutive communication satellite. The satellite was launched using an Ariane 4 rocket from French Guiana.
