3.3.3 The GNSS Reference
With most applications, SecureSync will be setup such that it utilizes a GNSS signal as the
primary (if not the only) timing reference.
SecureSync'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 SecureSync's timing system. The timing system uses the data to
control the System Time and discipline the oscillator.
While SecureSync’s default GNSS receiver configuration will likely be adequate for most
applications, it is advisable that you review the options and change settings as needed, par-
ticularly if you are experiencing poor signal reception.
