The Indian National Satellite SystemINSAT, 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.
The Indian Space Research Organisation is the national space agency of India. It operates as the primary research and development arm of the Department of Space (DoS), which is directly overseen by the Prime Minister of India, while the Chairman of ISRO also acts as the executive of DoS. ISRO is primarily responsible for performing tasks related to space-based operations, space exploration, international space cooperation and the development of related technologies. ISRO is one of the six government space agencies in the world that possesses full launch capabilities, can deploy cryogenic engines, can launch extraterrestrial missions and operate a large fleet of artificial satellites. ISRO is one of the four government space agencies to have soft landing (uncrewed) capabilities.

He was born on 2 July 1958, in a village called Kothavadi near Pollachi in Coimbatore district, Tamil Nadu state of India). Prior to taking this assignment he was with Indian Space Research Organisation and served as Director, ISRO Satellite Centre (ISAC), Bangalore. During his 36 years of service in ISRO, he had some of the major contributions, including two of the major missions of ISRO, namely Chandrayaan-1 and Mangalyaan. Annadurai has been listed among 100 Global thinkers of 2014 and topped the innovators list. His works are mentioned in textbooks of Tamil Nadu Board of Secondary Education
Kalpana-1 was the first dedicated meteorological satellite launched by Indian Space Research Organisation using Polar Satellite Launch Vehicle on 12 September 2002. The satellite is three-axis stabilized and is powered by solar panels, getting up to 550 watts (0.74 hp) of power. The METSAT bus was used as the basis for the Chandrayaan lunar orbiter mission of 2008.
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-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-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-1C was the third in the first generation INSAT series of satellites 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
INSAT-2B was the second satellite in the INSAT 2 Series that was successfully launched for telecommunication and meteorological observation. This India satellite was launched on 23 July 1993 from Kourou, French Guiana and Ariane-4 being its launch vehicle. INSAT-2B is placed in the geostationary orbit at a longitude of 93.5 degree East. The satellites also carries a search and rescue(SAR) transponder, a data relay transponder and also high resolution radiometer. This radiometer has a resolution of 2 km (1.2 mi) in the normal visible band and of 8 km (5.0 mi) in the thermal infra red band.
GSAT-7 or INSAT-4F is a multi-band military communications satellite developed by the Indian Space Research Organisation. 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.
Cartosat-2E is an Earth observation satellite developed by the Indian Space Research Organisation (ISRO), and is the seventh in the Cartosat series. It is designed to collect high-resolution, large-scale imagery for use in urban planning, infrastructure development, utilities planning, and traffic management.
INSAT-1D was 4th and the concluding multipurpose geostationary satellite of the INSAT-1 (first-generation seven-year responsibility for the operation of the INSAT space segment.
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$22 million).
Cartosat-2F is the eighth satellite in the Cartosat-2 Series. It is an Earth observation satellite launched on the PSLV-C40 mission by the Indian Space Research Organisation (ISRO).
GSAT-30 is a telecommunications satellite developed by the Indian Space Research Organisation (ISRO).
