SOG/COG used by the system is shown at the upper right corner of the ECDIS display. In the example below, COG
and SOG are from selected position sensors and this is indicated with the text "(pos)". Other text that denote
SOG/COG source are
(BOT): Bottom tracking dual-axis log
(CALC): Speed calculated from SOG
(WT): Water tracking log
(RDR): Mixed sources of COG and SOG in the connected radar
(POSN): Average of selected position sensors
(FILTER): Kalman filter
(MAN): Manual entry
Note that (pos), (bot), (wat) and (man) could come from direct interfaces of the system or from the connected radar.
