The ASR-GPS  is a high precision date and time module, which can be used as a master to
feed one or more clock or date displays.

The master / slave arrangement  ensures that all displays are perfectly synchronised.

A high precision reference oscillator is used for the timing, with a typical accuracy of +/- 3
seconds per month.

This is re-corrected whenever the module is in sight of 3 or more GPS satellites, which send it
high precision time data, referred to atomic standards.

The ASR-GPS is recommended for use in applications where a precist time reference is re-
quired and where the reference can be mounted in view of the sky.
