Aryabhata. Since then, India has made significant leaps in the vast and endless domain of space through Indian Space Research Organisation (ISRO), the nodal agency and flag-bearer of the Indian Space Programme. The purview of the Indian space programme includes a gamut of specialised fields such as remote sensing, astronomy and astrophysics, atmospheric sciences, and space sciences in general. The twin objectives of India's space programme are: Space discovery and exploration through space missions, and promotion of research and education related to space science in India. Besides, the space programme has several other functions including resource management such as mineral resources, agriculture, marine resources etc; environment conservation; internal security and terrorism; weather forecasting, disaster management, communication, etc. Commissioned in 1983, Indian National Satellite (INSAT), a series of multipurpose geostationary satellites launched by ISRO to conduct telecommunications, broadcasting, meteorology, and search and rescue operations. With nine operational communication satellites in the geostationary orbit, the INSAT system is one of the largest domestic communication satellite systems in the Asia-Pacific.

The INSAT satellites have application in the areas of educational TV services, television, satellite-aided search and rescue, disaster management and geopolitics (such as the SAARC satellite). It also helps in commercialising space programmes, such as launching communication satellites of other countries or agencies. In 1988, ISRO deployed several operational remote sensing satellites which provide disaster management support,
