Abstract
The paper describes a new electronic device that allows an easily measurement
of the drift between a reference time source (usually GPS) and an atomic
rubidium clock which is normally used in seafloor observatories. The Rubidium clock
is used in autonomous seafloor observatories to supply reference time for data acquisition
with the precision of milliseconds. During the deployment of seafloor observatory
the clock is synchronized with GPS. It is critical to evaluate the time drift
between the clock and the GPS, when the observatory is recovered. In fact, thanks
to an accurate drift measurement it’s possible to have a correct timestamp for data
series collected by seafloor observatory’s instruments. The device described in this
paper is composed by an Arduino mega shield integrated with other electronic circuits.
The device is easily customizable for different clocks in fact Arduino IDE allows
development of the desired features for the rubidium clock used in the specific application.
