The Government of India set up Space Commission and Department of Space- DOS in June 1972. Indian Space Research Organisation- ISRO under DOS executes Space programme through its establishments located in different places in India.
Indian space programme has been driven by the vision of Dr Vikram Sarabhai who is considered as “The Father of Indian Space Programme.”
The prime objective of Indian Space Research Organization- ISRO is to develop space technology and its application to various national tasks. ISRO has established two major space systems
1. Indian National Satelite-INSAT for communication, television broadcasting and meteorological services
2. Indian Remote Sensing Satellites- IRS system for resources monitoring and management.
ISRO has developed two satellite launch vehicles, PSLV and GSLV, to place INSAT and IRS satellites in the required orbits.
