Navigator Scout Badge post 2002
The Scout Activity badges from post 2002 are
circular with the Activity image on a blue background with a red border. The
Badge is worn on the left sleeve starting from the shoulder and going down in
order of achievement.
To earn the Navigator Scout badge they must achieve
the following
1. Using 1:50
000 and 1:25 000 scale Ordnance Survey maps:
a. Show that
you understand the meaning of scale, true, grid and magnetic north and can
recognise conventional map symbols.
b. Interpret
contour lines in terms of shape and steepness of terrain. Know the meaning of
topographical features such as valley, col, ridge, spur, etc.
c.
Show how to set a map with and without a compass. Be able to use
and give six-figure grid references. Demonstrate the use of a roamer to improve
accuracy.
d. Show how
to measure distances on a map and how to estimate timings for a particular
route.
e.
Show how to find north without the aid of a compass, by day or
night.
f.
Demonstrate your awareness of the latest developments in
electronic technology such as the Global Positioning System.
2. Be
familiar with traffic signs and signals as illustrated in the Highway Code.
3. With other
Scouts, accompany a motorist on a journey of at least 30 kilometres, taking it
in turns to act as navigator to a stated destination. The route should avoid
motorways and major roads and if possible should be cross-country, using a
variety of roads and lanes. There should be no prior route preparation.
4. Walk two
compass routes of at least 2 kilometres each. One route should have start and
end points defined on a map by an adult and the second by the Scout.
5. Demonstrate
an ability to:
a. Convert
grid bearings to magnetic bearings and vice versa.
b. Use back
bearings to check the route.
c.
Estimate current position using a compass.
d. Walk on a
bearing, including 'deviating from course', (the four right angles technique to
circumvent an obstacle).
Alternative B - air
1. Given
three headings and corresponding tracks, work out in each case the type and the
amount of drift in degrees. Illustrate each case by a simple diagram.
2. Demonstrate
with a compass how an aircraft can be turned on to various compass headings.
3. Choose one
of the following activities:
a. Draw on a
topographical air map a track for an imaginary flight of not less than 80
kilometres. Point out the landmarks that would show up on both sides of the
track in clear visibility at an altitude of about 600 metres.
b. Identify
on a topographical air map landmarks seen during a flight of about half an
hour's duration in clear weather
4. Illustrate
by means of a simple diagram how a fix can be obtained from two position lines.
Describe briefly two ways in which bearings can be obtained in an aircraft.
5. Show an
understanding of compass headings by completing the following two tasks:
a. Given the
true heading and the variation and deviation, work out the compass heading on
which the pilot should be flying.
b. Given two
sets of true, magnetic and compass headings, work out the variation and
deviation in each case.
6. Illustrate
latitude and longitude by simple diagrams.
7. Draw on a
topographical map the track between any two places not less than 100 kilometres
apart and measure the exact distance. Given the aircraft's air speed as 130
km/h, work out the time of flight from overhead starting point to overhead
destination in each of the following conditions:
a. with no
wind at all
b. with a
head wind of 30 km/h
c.
with a tail wind of 50 km/h
8. Demonstrate
your awareness of the latest developments in electronic technology such as the
Global Positioning System.
Alternative C - water
1. Have a
good working knowledge of charts, chart datum and symbols used.
2. Display an
aptitude in compass work by completing the following three activities:
a. Read a
mariner's compass marked in points and degrees and have knowledge of compasses
generally.
b. Know about
variation and avoiding deviation. Be able to correct a magnetic compass course
for variation and deviation to obtain a true bearing. Given a true bearing,
successfully adjust this to obtain a compass course.
c.
Understand how compass error can be found from a transit
bearing.
3. Complete
two of the following:
a. Understand
how a position may be found from two intersecting position lines.
b. Understand
what is meant by a 'cocked hat' position and how to use it safely. Plot a
position from any three cross bearings
c.
Plot a position using the 'running fix' method.
d. Plot a position
using a combination of compass bearings and any one or more of the following:
·
satellite navigation system
·
vertical sextant angle
·
horizontal sextant angle
·
line of soundings
·
transits
4. Be able to
use tide tables and tidal stream atlases.
5. Understand
the use of the marine log to obtain distance run and speed.
6. Understand
the buoyage system for United Kingdom coastal waters and other methods of
marking dangers and channels.
7. Demonstrate
your awareness of the latest developments in electronic technology such as the
Global Positioning System and electronic charts.
8. Undertake
a coastal voyage of between four and six hours acting as navigator. A log
should be kept showing courses steered, distance run, navigation marks passed
and weather experienced. During the voyage:
·
Plot the estimated position every hour by keeping up the dead
reckoning.
·
Whenever appropriate, and not less than once per hour, plot an
observed position by bearings or other means of obtaining a fix.
The voyage
should be planned on the chart beforehand using tidal streams to the best
advantage and giving hourly courses to steer for an assumed speed.
Alternative D - GPS Navigation
1. Demonstrate
an awareness of the Global Positioning System (GPS) to include:
a. how it
works
b. ownership
and control of the system
c.
benefits to society
d. what
factors affect accuracy
2. Programme
a hand-held GPS receiver to perform the following functions:
a. Find your
location (grid reference and latitude/longitude) and record it
b. Enter the
grid reference of a local landmark and navigate to the waypoint
c.
Enter the latitude/longitude coordinates of a nearby point and
navigate to the waypoint, checking the accuracy
d. Walk on a
bearing using the GPS and a map.
3. Demonstrate
an understanding of the difference between Ordnance Survey and
latitude/longitude coordinates.
4. Using an
Ordnance Survey map (1:25 000 or 1:50 000 scale) plan a route of at least 4km
that contains a minimum of 10 waypoints. Discuss the features and challenges
that exist along the route. Programme the route into a hand-held GPS and
undertake the journey.
5. Sign up to
a geocaching website. Find out about geocaching and demonstrate an
understanding of what is involved in both locating and placing a geocache.
6. Demonstrate
an understanding of the safety and environmental aspects of geocaching, e.g.
relevant Activity Rules in chapter nine of Policy, Organisation and Rules;
Highway Code; Countryside Code and guidelines produced by the Geocaching
Association of Great Britain (GAGB).
7. Find five
geocaches using a GPS, at least 3 of which must be 'multi-caches' with at least
two waypoints. Discuss the accuracy of the information provided and of the GPS
receiver you used.
8. With adult
assistance where necessary:
a. Plan,
assemble and hide 2 caches, one of which should be a multi-cache. The planning
should involve making sure the location is suitable and that other navigators
have proper access to the land and terrain
b. Either
submit your caches to a geocaching website, or give the details to other Scouts
to successfully find the caches.
