5.1.6 Troubleshooting GNSS Reception
If SecureSync reports Holdover and/or Time Sync Alarms caused by insufficient GNSS recep
tion:
When a GNSS receiver is installed in SecureSync, a GNSS antenna can be connected to the
rear panel antenna connector via a coax cable to allow it to track several satellites in order for
GNSS to be an available input reference. Many factors can prevent the ability for the GNSS
receiver to be able to track the minimum number of satellites.
With the GNSS antenna installed outdoors, with a good view of the sky (the view of the sky is
not being blocked by obstructions), SecureSync will typically track between 5-10 satellites (the
maximum possible is 12 satellites). If the antenna’s view of the sky is hindered, or if there is a
problem with the GNSS antenna installation, the GNSS receiver may only be able to a few
satellites or may not be able to track any satellites at all.
When GNSS is a configured time or 1PPS input reference, if the GNSS receiver is unable to
continuously track at least four satellites (until the initial GNSS survey has been completed) or at
least one satellite thereafter, the GNSS signal will not be considered valid. If no other inputs
are enabled and available, SecureSync may not initially be able to go into time sync. Or, if
GNSS reception is subsequently lost after initially achieving time sync, SecureSync will go into
the Holdover mode. If GNSS reception is not restored before the Holdover period expires
(and no other input references become available) SecureSync will go out of sync. The GNSS
reception issue needs to be troubleshot in order to regain time sync.
