Indian Space Research Organisation
ISRO built India's first satellite, Aryabhata, which was launched by the Soviet Union on 19April 1975. It was named after the mathematician Aryabhata. In 1980, Rohini became the first satellite to be placed in orbit by an Indian-made launch vehicle, SLV-3. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites and earth observation satellites. Satellite navigation systems like GAGAN and IRNSS have been deployed. In January 2014, ISRO used an indigenous cryogenic engine in a GSLV-D5 launch of the GSAT-14.
BeiDou Navigation Satellite System
The first satellite, "BeiDou-1A", was launched on 30 October 2000, followed by "BeiDou-1B" on 20 December 2000. The third satellite, "BeiDou-1C" (a backup satellite), was put into orbit on 25 May 2003. The successful launch of "BeiDou-1C" also meant the establishment of the BeiDou-1 navigation system.
