Triangulation. See pic (newcomers, open in new tab, zoom-in for details)

Where are you (on the map)? Take a bearing on two (or three) markers in the field which are also on the map. Orientate on the map, draw bearings, intersection is your position. Use same method to find position of a destination in the field.

Choose markers or take given markers. Sequence is significant to comms. Time stamp(s) and order (is) critical. Hours, minutes, seconds on clock can be related to 360 degrees of a Compass Rose.

Here are examples of triangulation. First an illustration of the basic method and then applications from past decodes. Each has been moar or less reliable but still open to further interpretation.

Infographic on method: Take a bearing (on a map), take a bearing (from markers), find heading and go.

Nothing ventured, nothing gained.
