3.8.7 Calculated Values

Processed dynamic ship data such as position, SOG etc. is generated by NMEA sentences.

Exceptions:

If "Calc" is displayed on the sensor analyze screen, this means that this sentence is used for

calculating dynamic ship data.

ROT out of HDT

ROT direction left / right -/+ will be calculated out of the HDT Message, if a TIROT sentence

(only “TI”-Talker devices are valid) is not connected.

ROT > +10°/min

Output +720°/min

ROT < -10°/min

Output -720°/min

Other

Output 0°/min

COG information out of VBW

COG will be generated out of VBW, if HDT is available. In this case the atan2 of the

longitudinal and transversal speed plus heading is basis of the calculation.

Longitudinal/Transversal SOG from VBW

If VBW is available, SOG is also calculated without HDT.
