this case the GNSS port method as described in section 3.5.7.2.

This method is named the ‘closed coupled mode’. By using the POS MV
GNSS port the corrections are applied straight at the POS MV’s GNSS
board.
The formats RTCM v2.x, RTCM v3.x, CMR/CMR+ and CMRx are
supported.
Both GPS and Glonass corrections are used. RTK fix is also available
when the vessel is moored.
