Automatic Switch to the Next Waypoint in a
Route
A route is made up of a minimum of three points. The start point A, the
first destination waypoint B and the second destination waypoint C.
When following a route from A to B then C, C automatically becomes the
active waypoint when B is reached or passed.
AB and BC segments make 2 angles: one is greater than 180° (angle
D
)
and the other is smaller than 180° (angle ß).
The change of active waypoint occurs differently depending on the angle
the vessel is moving in.
Vessel moving in the angle greater than 180° (angle
D
):
The change of active waypoint occurs when the vessel crosses the BB’
line (X point) where the BB’ line is the perpendicular line to the AB
segment.
Vessel moving in the angle smaller than 180° (angle
ß):
The change of active waypoint occurs when the vessel crosses the BB”
line (Y point) where the BB” line is the bisecting line to the angle made by
the AB and BC segments.
