Manually Setting the GNSS Position

The exact geographic position (location and elevation) of the antenna your VersaSync unit—
and thus its onboard GNSS receiver—is a major factor for VersaSync to calculate an accurate
System Time from the GNSS reference.
Normally, the onboard GNSS receiver will track and adjust the antenna position during the so-
called GNSS self survey , which is performed during initial commissioning of a VersaSync unit,
or when rebooting a unit after it had been powered down for some time ("cold start").
