The Direction of an Object
• The direction of an object from a point can be specified
in either compass directions or bearing directions.
• The Watch includes both compass directions and
bearing directions.
The Compass Directions
• The compass directions are shown in the adjacent
table.
• For example, in the figure on the left, the compass
direction of object B from point A is due East. The
compass direction of object C from point A is Southeast.
The compass direction of object D from point A is
Northwest.
The Bearing Directions
• The Bearing direction of an object is defined as the
angular difference between North and the object.
(Assume 0°for due North, and the measuring range is
from 0° to 359°).
• For example, in the figure on the left, the bearing
direction of object B from point A is 90°. The bearing
direction of object C from point A is 135°. The bearing
direction of object D from point A is 315°.
