2011 Compass Rose Geocoins
The Compass Rose Geocoin® is about the critical importance
of the sun and navigation. Navigation by the sun was practically second
nature a thousand years ago, even though it was not as accurate without
special tools as today's methods. It was very important to know where
the sun tracked across the sky and exactly where it would rise and set
depending on the season. Since the 1700s, knowing the sun's declination
was imperative to calculate longitude. Knowing how to gain longitude was
very important to calculate accurate navigation and map making.
