The idea of having domestic geostationary satellite system for India to meet the Telecommunication and TV broadcasting needs of the country was first mooted by Late Dr. Vikram Sarabhai in the 60s. Several studies were conducted before India embarked on building and owning the India National Satellite System- INSAT.

In 1975, at the highest level of the Government, decision was taken that the communication network in India will have a satellite component as part of building the National Infrastructure.

The INSAT programme is joint venture of four agencies of the Government of India, namely Department of Space, Dept. of Telecommunications, Ministry of Information & Broadcasting and Department of Science and Technology. The overall co-ordination and management of the INSAT system rests with the INSAT Co-ordination Committee (ICC) in which Secretary Department of Space is Chairman and the Secretaries of Dept. of Telecommunications, Ministry of Information , Broadcasting and Department of Science and Technology & other concerned departments are members. The ICC is assisted by inter- agency Technical Advisory Group (TAG).

Network Operations Control Center under Department of Telecommunication created to control the transmissions from ground segment (satellite earth stations) along with the Master control Facility under Department of Space to manage the operation of Satellites (INSAT) in orbit. At the time of operationalisation of INSAT 1 A the NOCC funtions were carried out by using the Sikandrabad Communications Earth Station Antenna and working from one of the ports of the RF power divider. A seperate NOCC earth station was made available in the first half of 1983 when the limited domestic SATCOM network was working through two leased INTELSAT transponders.

NOCC provide the network clearances before start of operations from any earth station accessing Satellite and also carried out the Monitoring and on line operational control & co-ordination.


As on date seperate 11 metre antnenna for C Band, Extended C Band and Ku Band are available with NOCC along with "Integrated Satelite Network Monitoring System (ISNMS)", C Band, Extended C Band, Ku band and S Band monitoring set ups for 24x7 monitoring, control and cordination for space segment use from India.
