15.5 Source of Navigation Data
The figure below shows how various sources of navigation data are chosen. "SOG, COG" is speed over ground and
course over ground, respectively. "Speed" is speed over water, "Drift" is the difference between speed over water
and speed over ground. Docking speed components are bow speed (transversal), stern speed (transversal) and center
speed (longitudinal).
Heading used by the system is shown at the upper right corner of the chart radar display. In the example shown
below, heading is received from a gyrocompass and it is shown without additional text, meaning the value is
referenced to true North. Additional gyro-related text which may appear are "(mag)" if the value is referenced to
magnetic North, "(man)" if the value has been manually entered; or "(corr)", which is displayed in red, if the value
includes gyro correction.

ROT used by the system is shown in the Speed/Course page of the Sensors dialog box. The Rate Gyro field shows
the text "(calc.)" when the system calculates ROT from movement of heading. No text is shown when the value is
received from an ROT gyro.
