2. INDIAN NATIONAL SATELLITE SYSTEM(INSAT) The national satellite system, established in 1983 , is joint venture of the Indian department of space , DOS , the department of telecommunication (DOT), the Indian meteorological department (IMD), all Indian radio (AIR) and doordarshan (DD.) It is largest communication system in world. It serves the television and communication needs of India. It carries 199 transponders and high resolution radiometer(VHRR) and CCD cameras for metrological imaging.

3. FEATURES OF INSAT SATELLIATE INSAT was a multipurpose satellite system for telecommunication , broadcasting, metrology and search and rescue services. INSAT was largest domestic communication system in Asia pacific region with 11 stellates in operation. INSAT is a series of multiparous geo-stationary satellites launched by ISRO. EDUSAT , launched by geo synchronous launch vehicle,(GSLV-F01)in September 2004,is India's first thermatic satellite dedicated exclusively for educational services. INSAT is being used to provide educational TV(ETV)service for primary school children in various languages. INSAT provided facility of telemedicine. INSAT has been a major catalyst for the expansion of television coverage in India.

4. INSAT SEREIS Oct. 1982 first satellite in INSAT series launched: INSAT 1A-MISSION abandoned due technical failure. Aug 1983 INSAT 1B operational until 1990. July 1988 INSAT 1C abandoned 1989 due to power system failure. June 1990 INSAT 1D last in the first INSAT series. June 1992 INSAT 2A first multipurpose Indian communication satellite becomes fully operational. Launches of INSAT series satellite continue approximately every two to three years.

5. INSAT TODAY Todays INSAT has 11 operational satellite. In keeping with Dr.sarabhai’s vision INSAT sat com application now include.. Telemedicine connects rural health care facilities with modern urban medical centers. INSAT is also providing disaster warning to the receiver installed along the cyclone-prone East cost of the country. INSAT has improved the weather forecasting. ISRO INSAT satellite

6. INDIAN CONTRBUTION TO SATALLITE APPLICATION INDAIN space programme driven by vision of Dr.vikram sarabhai consider as the father of Indian space programme. Vikram sarabhai was the founder of first Indian space center named as vikram sarabhai space center which is now known as ISRO. India also launched its own APPLE (Ariane Passenger payload Experiment), an experimental communication satellite.

7. ABDUL KALAM FOR I.S.R.O Before his term as president , he worked as an aerospace engineer with Defence Research and Development Organization (DRDO) and Indian space Research Organization(ISRO). Kalam is popularly known as the Missile Man of India for his work on the development of ballistic missile and launch vehicle technology. Kalam a man with no authority over nuclear physics but who just carried on the works of Homi J. Bhabha and Vikram Sarabhai. A.P.J. Abdul kalam was the director of India’s first Indigenous satellite launch vehicle (SLV-3).

11. PERFORMANCE OF INSAT Television reaches to about 85 percent of the population through over 1000 TV transmitters linked via INSAT. Educational programmes for over 100 hours are telecast every week. INSAT system has become a powerful tool for training and developmental education and is used by various agencies to provide continuing education, conduct in-situ training. A pilot project that started in November , 1996 in a tribal district of Madhya Pradesh in Central India is now in progress to educate the tribal community on various aspects of health, hygiene, family planning, women’s rights, etc.

12. Conclusion: Space-based technologies play an increasingly critical role in the maintenance and development of national and international infrastructures. More than 130 states have interests at stake either as space-faring nations or indirectly benefiting from the use of commercial satellites. INSAT for communication services and Indian Remote sensing(IRS) satellite for management of natural resources. Here Geostationary satellite launch vehicle is used for launching INSAT Type of satellite.
