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.
Carl E. Duckett
On October 4, 1957, America was shaken by the launch by the Soviet Union of the first artificial satellite, "Sputnik I". The U.S. Air Force and the CIA assembled a highly secret Telemetry and Beacon Analysis Committee (TABAC) to analyze the signals recorded from the launch at Tyuratam and those heard all over the world from "Sputnik". From his work in Jam Session, Duckett was asked to be a leader in the TABAC effort. It required about 18 months to calibrate the signals and understand how they related to the launch vehicle characteristics. The payoff, however, was significant; for the next two decades this provided the U.S a major window into the operation of Soviet missiles.
