Triangulisation

Question 1

What is Triangulation

Answer 1

Triangulation Can be used to fix your position when you can recognise features on the ground and on the map but are unable to fix you exact position on the map.

Question 2

Steps of Triangulation

Answer 2

1- Select three prominent widely spaced features that you can recognise on the map and on the ground

2- Using the compass take a magnetic bearing to the first feature

3- convert the magnetic bearing into a grid bearing

4- Convert the grid bearing to a back bearing and plot this back bearing on the map with a thin line from the feature.

5- Carry out the above procedure until you have plotted the back bearings on the map from each of the features you have selected

6- These lines will either intersect to locate your position or form a small triangle of error
