- Innovations: Atomic Clock
This primary atomic frequency standard, a hydrogen maser, served as the stable frequency source for the master clock.
A cesium clock like this was tested on the NTS-2 satellite to see if clocks could keep accurate time in space.
This atomic clock was built for the first GPS satellites in the late 1970s.
This represents the first commercially available chip-size atomic clock.
This represents the first demonstration of a tiny atomic clock.
This is the master clock used at the Goldstone, California, Deep Space Network station from about 1983 to 2006.
Length: 7 Minutes, 3 Seconds
In the 1990s, the NIST-7 was the most accurate clock in the country and helped keep the GPS clocks synchronized.
A rubidium clock like this was tested on the NTS-2 satellite to see if clocks could keep accurate time in space.
This atomic clock was built for the first GPS satellites in the late 1970s.
