Deleting the GNSS Receiver Position

The SecureSync timing system requires the exact geographic position in order to calculate the
exact system time from the GNSS signal.
The Delete Position command deletes the GNSS antenna position data that is stored in the non-
volatile memory of the GNSS receiver.
The deletion of the position data will automatically initiate a new GNSS self survey , provided:
a GNSS antenna is connected to SecureSync
the GNSS receiver can track at least four satellites continuously
and the GNSS receiver it is configured to operate in Standard Mode (see "Selecting a
GNSS Receiver Mode" on page 172).
The objective of the GNSS Survey is to re-discover the current antenna position.
Relocating SecureSync
The Delete Position command may need to be used if a SecureSync system is physically moved,
and it did not self-initiate a new survey automatically, as is the case with u-blox M8T-series
receivers (see also "Determining Your GNSS Receiver Model" on page 170). Note that neg
lecting to delete the old position data and discover the new position data will cause
SecureSync not to go into synchronization state.

Note: A self survey will require at least 2000 seconds (33 minutes).
Software versions 5.4.5 and above by default will initiate a resurvey on
