HOME BASE
By setting the HOME BASE position you allow BroadShield to use this location as
a reference position for spoofing detection: Should BroadShield detect that the
geographic position reported by SecureSync's GPS receiver seems to move bey-
ond the set Alarm Threshold (even though SecureSync does not move), an
alarm will be triggered.
The standard use case is to make your GNSS 1 Position your HOME BASE:
A less common use case may be that you want to pre-set the unit's position for
later use e.g., if the SecureSync unit will be deployed in a different location: Set a
position manually by entering lat/long (format: xx.xxxxxx degrees) and alt. Note,
however, that this may cause a spoofing alarm, since BroadShield detects a dif-
ference between the HOME BASE position and the GNSS position.
