INSAT-1C was the third in the first generation INSAT series of satellites (termed as INSAT-1) built by Ford Aerospace to satisfy the domestic communication requirement of India. The Govt. agencies using its services were All India Radio, Doordarshan, Department of Space and Indian Meteorological Department [1]
INSAT-1C was launched from Guiana Space Centre in Kourou using Ariane 3 rocket on July 21, 1988. At launch, it had a mass of 1,190 kilograms (2,620 lb), and an expected operational lifespan of seven years. The satellite was positioned at 93.5° East longitude in geostationary orbit
INSAT-1C carried 3 payloads on board to provide communication services to Indian Meteorological Department, Department of Telecommunications and Department of Space:
INSAT-1C mission was a success and lasted for about 13 years because the satellite got another 6 C-band transponders and 2 S-band transponders when a power system made one more bus [3] [4]
The Indian National Satellite System or INSAT, is a series of multipurpose geostationary satellites launched by ISRO to satisfy the 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.
The GSAT satellites are India's indigenously developed communications satellites, used for digital audio, data and video broadcasting. As of 5 December 2018, 20 GSAT satellites of ISRO have been launched out of which 14 satellites are in service.
INSAT-4C was an Indian communications satellite which was lost in a launch failure in 2006. Had it reached orbit, it would have formed part of the Indian National Satellite System. Launched in 2007, it was intended to have operated in geostationary orbit at a longitude of 73.97° east. The INSAT-4CR satellite, launched in September 2007, replaced it.
INSAT-3B is an Indian communications satellite which was built by the Indian Space Research Organisation and operated by Indian National Satellite System.
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-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-3D is a meteorological, data relay and satellite aided search and rescue satellite developed by the Indian Space Research Organisation and was launched successfully on 26 July 2013 using an Ariane 5 ECA launch vehicle from French Guiana. The satellite has many new technology elements like star sensor, micro stepping Solar Array Drive Assembly (SADA) to reduce the spacecraft disturbances and Bus Management Unit (BMU) for control and telecom and telemetry function. It also incorporates new features of bi-annual rotation and Image and Mirror motion compensations for improved performance of the meteorological payloads.
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-4A was the first one in the INSAT-4 Satellites series, providing services in the Ku and C band frequency bands. At the time of launch, it was the heaviest satellite India had produced. The Ku transponders cover the Indian main land and C-Band transponders cover an extended area. It has a dozen Ku transponders and another dozen of C-band transponders. This spacecraft was placed at 83°E along with INSAT-2E and INSAT-3B, by Ariane launch vehicle (ARIANE5-V169).
GSAT-12 is communication satellite designed and developed by the Indian Space Research Organisation. It is the second satellite to be launched and placed on a GTO using PSLV.
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.
GSAT-7 or INSAT-4F is a multi-band military communications satellite developed by ISRO. The Indian Navy is the user of the multi-band communication spacecraft, which has been operational since September 2013. According to defense experts, the satellite will enable the navy to extend its blue water capabilities and stop relying on foreign satellites like Inmarsat, which provide communication services to its ships.
GSAT-16 is the 11th Indian communication satellite, meant to increase the number of transponders available for satellite-based telecommunication, television, and VSAT services in India. GSAT-16 is similar to GSAT-15 with each satellite weighing 3,150 kg and having power generation capacity of 6.8 kW.
INSAT-3DR is an Indian weather satellite built by the Indian Space Research Organisation and operated by the Indian National Satellite System. It will provide meteorological services to India using a 6-channel imager and a 19-channel sounder, as well as search and rescue information and message relay for terrestrial data collection platforms. The satellite was launched on 8 September 2016, and is a follow-up to INSAT-3D.
GSAT-17 is an Indian communications satellite. Built by ISRO and operated by INSAT, it carries 24 C-band, 2 lower C-band, 12 upper C-band, 2 CxS, and 1 SxC transponders. It additionally carries a dedicated transponder for data relay (DRT) and search-and-rescue (SAR) services. At the time of launch, GSAT-17 was the heaviest satellite built by ISRO.
INSAT-1D was 4th and the concluding multipurpose geostationary satellite of INSAT-1 series. It was launched on June 12, 1990.
GSAT-30 is a telecommunications satellite developed by the Indian Space Research Organisation (ISRO).
