Sentences with phrase «than microwave atomic»

The higher frequencies mean that optical clocks «tick» faster than microwave atomic clocks and could thus provide time - stamps that are 100 to 1,000 times more accurate, greatly improving the precision of GPS.

Not exact matches

The second is currently defined by caesium atomic clocks, but optical clocks promise higher precision because their atoms oscillate at the frequencies of light rather than in the microwave band, so they can slice time into smaller intervals.

The accuracy and the stability of optical clocks are mainly based on the fact that the frequency of the optical radiation used is higher (by several orders of magnitude) than that of the microwave radiation which is used in cesium atomic clocks, which makes optical clocks much more precise than cesium clocks.
