This module is specially designed to suit the Pilot needs. The Pilot builds his own Ship's profile
database and can select the proper profile when entering a ship.
The GPS mode is automatically switched to Dead Reckoning (D.R.) mode in the case of loss of
signal from the GPS.
In the D.R. mode, ECDIS calculates the ship's position according to the last position received
and the course and speed acquired by ECDIS.
IMPORTANT
Dead Reckoning is possible only when ECDIS receives course and speed information
from the gyro/log sensor.
