In this example, SecureSync tracked no less that 6 satellites for the entire hour.
Out of the entire hour, it was tracking 6 satellites for a cumulative total of 151
seconds (not necessarily in a row). For the duration of the hour, it was tracking, 7,
8, 9, 10 and 12 satellites for a period of time. Because it was tracking at least at
least one satellite for the entire hour, this Quality value is Q=3600.
Note: If SecureSync is not connected to a GNSS antenna, this log will
remain empty.
System Log
Displays log entries related to the Timing System events and daemon events
(such as the Alarms, Monitor, Notification, or SNMP daemons starting or stop-
ping, etc.)
Timing Log
Displays log entries related to Input reference state changes (for example, IRIG
input is not considered valid), antenna cable status. Examples include:
GRGR = GNSS Reference
1
antenna fault: The GNSS Antenna Problem
alarm indicates the GNSS receiver has detected an over-current or under-
current condition (an open or short exists in the GNSS antenna cable, or the
GNSS antenna is not connected to SecureSync). The receiver will attempt
to continue the normal acquisition and tracking process regardless of the
antenna status.
GR antenna ok: The antenna coax cable was connected at this time or an
open or short in the antenna cabling was occurring but is no longer being
detected.
Update Log
Displays log entries related to software updates that have been performed.
