4.4.3 Configuring GPS Notification Alarm Thresholds
VelaSync allows you to configure Minor and Major alarm thresholds for the GNSS receiver.
This is done by setting the minimum number of satellites the receiver can track for a set
time before an alarm is triggered. If both conditions are met, i.e. the reception quality falls
below the set number of satellites for the set amount of time, an alarm is triggered.
The alarm notification feature described below allows you to be notified of a potential
reception issue BEFORE the GNSS reference becomes invalid. This may be useful e.g., to
notify system operators of a deteriorating signal reception before VelaSync loses the
GNSS reference.
Note that VelaSync itself has a pre-defined minimum number of satellites that must be
tracked in order for GNSS to be considered a valid reference. The minimum number of
satellites depends e.g., on your receiver mode, the GNSS signal reception in the area
where your antenna is located, and the type of receiver in your unit. In Stationary mode,
