NAVIGATION
& RANGING
it analyzes sounds
to determine distance
and direction

- Images near the poles seem
larger than they really are.

(Globe):
Provides accurate information
about distances and
directions between
two points.
Robinson Projection
are both distorted
appear flatter than they really are.
Compass Rose:
Shows you the
