The GNSS Reference

With most applications, VersaSync will be setup such that it utilizes a GNSS signal as the
primary (if not the only) timing reference.
VersaSync's GNSS receiver utilizes the signal provided by the GNSS antenna.
The GNSS receiver analyzes the incoming GNSS data stream and supplies the GNSS time and
1PPS (Pulse-Per-Second) signal to VersaSync's timing system. The timing system uses the data to
control the System Time and discipline the oscillator.
While VersaSync's default GNSS receiver configuration will likely be adequate for most applic-
ations, it is advisable that you review the options and change settings as needed, particularly if
you are experiencing poor signal reception.
