GPS CLOCK SYNCHRONISATION MODULE
In many measurement applications it is important to have very accurate timing of the measurement.
This is required since the measurement algorithm demands it and/or that the installation site is
remote and no periodic communication with clock synchronization can be done. A very effective
way to achieve this is to synchronize the instruments internal clock with the atomic clocks of the
global positioning system (GPS) satellites.
With accurate real-time clock synchronization, the comparison between events such as sags/swells or
transients between different sites in the electrical network can be made with high accuracy, even if
the distance between the sites is large.
The GPS clock synchronization module can be used with the Unipower UP-2210. In order for the
synchronization to work, the units must be equipped with the appropriate software as well as the
necessary peripheral hardware.
Below is a mechanical drawing of the optional GPS unit delivered by Unipower.

This chapter covers the use of the GPS synchronization module with the UP-2210 family of
instruments.
