3.6.4Track plotting method and interval for own ship track

In drawing the own ship track, first the ship’s position fed from position-fixing equipment is stored into the unit’s memory at an interval of time or distance. A shorter interval provides for better reconstruction of the track, but the storage time of the track is reduced. When the track memory becomes full, the oldest track is erased to make room for the latest.
