Both atomic clock designs have proved resistant to radiation effects, with GIOVE-B's passive hydrogen maser
- designed to lose less than one second every three million years - running so well that errors cannot be spotted easily over the general measurement system noise.
OroliaAbout T4ScienceT4Science, a Swiss company of the Orolia group, is a global leading designer and manufacturer of advanced, high performance hydrogen maser
But these are too big, too heavy, and too likely to need servicing to put on the satellite, so instead the local oscillator signal will be piped up from the tracking stations, each of which has its own hydrogen maser
They also rely on a wide range of Symmetricom precise timing solutions, including their hydrogen maser
clock for maintaining standard time as well as four Symmetricom time servers for distributing time across its internal network.
The new earth observatory in Ny-Ealesund shall therefore procure an active hydrogen maser
When applied to a hydrogen maser
, which produces microwave radiation of a specific frequency, a nonlinear correction to quantum mechanics would mean the maser's output frequency depends on the number of excited hydrogen atoms pouring into the cavity where the device amplifies the radiation.
