Introduction
Sponsored by Ordnance
Survey, the badge can be undertaken three different ways - land navigation
(alternative 'A'), air navigation (alternative 'B') and sea navigation
(alternative 'C'). This page concentrates on alternative A. (If you
would like to see the requirements for the other alternatives, click on a badge to visit the requirements page on ScoutBase.)
 
Requirements
The requirements for land-based navigation
are as follows. Each requirement contains a hyperlink to a page on a
special Ordnance Survey website called 'Mapzone', where you can find interactive
activities on that particular element. (Visit the 'Mapzone' home page here.)
-
Using 1:50 000 and 1:25 000 scale Ordnance Survey maps:
-
Show an understanding of the meaning of scale,
and true, grid and
magnetic north, and recognise
conventional map
signs. (NOTE: You can download or print out
a complete set of map symbols via this last link.)
-
Interpret contour lines in terms of shape and steepness of terrain,
and know the local names and meanings of topographical features such as
col, ridge and spur.
-
Show how to set the map with and without a compass. Be able to use
and to give six-figure grid references and demonstrate the use of a
Romer measurer to improve accuracy.
-
Show how to measure distance on the map and how to estimate timings
for a particular route.
-
Show how to find north without the aid of a compass, by day or night.
-
Demonstrate awareness of the latest developments in electronic
technology such as the Global Positioning System (GPS).
-
Be familiar with the traffic signs and signals as illustrated in The
Highway Code.
-
With other Scouts, accompany a motorist, each Scout taking it in turns to
act successfully as a navigator for a journey of at least 30 kilometres. The
route should avoid motorways and other major roads and, whenever possible,
should be ideally a cross-country route using a number of different roads
and lanes. The journey should also include navigating with no previous
preparation of the route.
-
Accurately complete two compass routes of at least two kilometres, one
with the beginning and end as defined on a map by the assessor, and the
second chosen by themselves. During these exercises, show that they can:
-
Convert grid bearings to magnetic bearings, and vice versa.
-
Use back bearings to check their route.
-
Pinpoint their position using a compass.
-
Demonstrate methods of route selection, including aiming off, and the
four right angles and step counting techniques.

'Map Reading Made Easy' leaflet (1.4Mb), which covers some of the above, here. |
