4. NAVIGATION PLANNING
4.1 Entering Waypoints
In navigation terminology a waypoint is a
particular location on a voyage whether it be
a starting, intermediate or destination
waypoint.
The GP-150-DUAL can store 999 waypoints,
numbered from 001-999. Waypoints can be
registered four ways:
• by cursor
• by MOB position or event position
• at own ship's position, and
• through the waypoint list.
Waypoints are mutually entered when the
navigators are sharing data.
Entering waypoints by the cursor
1) Press the WPT RTE key to show the
Waypoint/Route menu.

A window similar to the one shown in Figure
4-3 appears. The waypoint's position and
date and time registered appear on the first
and second lines. Waypoints are
automatically given the youngest empty
waypoint number and this number appears
on the third line. You may, however, assign a
different number. If the waypoint shares the
same position with a mark, the mark's
position and date and time entered are
registered as waypoint data.
If the waypoint memory is full, the waypoint
number line in the window is blank. In this
case waypoints cannot be entered unless a
waypoint is written over or erased.
