Each Galileo satellite has two master passive hydrogen maser atomic clocks and two secondary trilaterating the difference in received signals from multiple satellites.
13.
Its cesium atom and hydrogen maser clocks have now been harnessed to tick off the passage of time on the World Wide Web.
14.
Another test involving a space-borne hydrogen maser increased the accuracy of the measurement to about 10 " 4 ( 0.01 % ).
15.
The site also hosts a hydrogen maser, a standard feature for radio telescopes that can also serve to receive telemetry from deep space missions.
16.
According to its original plan, QZSS was to carry two types of space-borne atomic clocks; a hydrogen maser and a rubidium ( Rb ) atomic clock.
17.
The observatory is also equipped with a hydrogen maser that maintains time standard stability to one part in 10 15 in order to facilitate data correlation.
18.
Hyperfine splitting is a splitting in the energy levels of an atom caused by the interaction between the magnetic moment of the Ramsey's hydrogen maser, is known with great precision.
19.
There are said to be some performance improvements for owners of Power Macintosh system, but in my experience it may be necessary to employ a hydrogen maser clock to measure them.
20.
He was awarded the Nobel Prize in Physics in 1989 " for the invention of the separated oscillatory fields method and its use in the hydrogen maser and other atomic clocks ".
