• “HDT”, “HDM”, “RMC”, “GGA”, “GLL”, “VTG”, “WPL”, “GNS” and “BWC” are SENTENCES of the NMEA0183.

•If BRG INPUT is set to “GPS”, “RMC” of NMEA2 connector or COG (Course Over the Ground) of “VTG” a bow it receives as a direction, even if there is no direction information (compass etc.) in NMEA1 connector, the screen display of the North rise etc. is possible.

However, direction accuracy falls when the speed of a ship is set to 2 or less kts, or when exceeding 3 kts a bow it does not receive as direction data. Moreo, the influence of measurement position accuracy or a current an actual bow it may differ from a direction.
