Other Designations: Applications Technology Satellite. Class: Technology. Type: Communications. Nation: United States. Agency: NASA, NSF. Manufacturer: Fairchild.

In addition to its technology experiments, ATS-6 became the world's first educational satellite. During its 5 year life, ATS-6 transmitted educational programming to India, the US and other countries. The vehicle also conducted air traffic control tests, was used to practice satellite-assisted search and rescue techniques, carried an experimental radiometer subsequently carried as a standard instrument aboard weather satellites, and pioneered direct broadcast TV. The satellite also played a major role in the Apollo/Soyuz docking in 1975 when it relayed signals to the Houston Control centre. It was boosted above GEO when thruster failures threatened to prevent further control of the spacecraft. Spacecraft: 9 m diameter deployed antenna reflector. Pointing accuracy 0.1 deg.2 half cylinder drum arrays on booms provide 645 W BOL.3 axis stabilised. Payload: VHRR (Very High Resolution Radiometer) instrument, millimetre wave propagation experiment, L-band communications package, C-band communication equipment
