15. Navigation Sensors
SOG/COG used by the system is shown at the upper right corner of the Chart Radar display. In the example below,
COG and SOG are from chosen position sensors and this is indicated with the text "(pos)". Other text which denote
SOG/COG source are
(BOT): Bottom tracking dual-axis log
(CALC): Speed calculated from SOG
(WAT): Water tracking log
(RDR): Mixed sources of COG and SOG in the connected radar
(POSN): Average of chosen 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.
