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.

During the Cultural Revolution, Sun was appointed as the chief scientist of the Chinese satellite project. On April 24, 1970, the first Chinese space satellite, Dong Fang Hong I, was successfully launched. On March 3, 1971 the satellite "Shi Jian I" was launched. In 1975, China's first returning satellite was successfully launched. In 1984, China's first synchronized experimental communication satellite, Dong Fang Hong II was launched. Sun was the chief designer of all of them.
