# Advice 1: How to calculate the azimuth

On any terrain you can clearly navigate using a compass. But to learn to determine the direction, you need to know how to calculate the azimuth. To do this, measure the angle between the direction to the object to which you want to move, and the Northern direction.
You will need
• - compass;
• - a small steel object;
• - line or direct splinter.
Instruction
1
First, check that compass. To do this, take steel object (keys, scissors, etc.). Put the compass on a horizontal plane and moving the attachment of the arrow if it is. The arrow should point the blue end to the North. Take prepared steel object and setting the opposite end of the arrow that points North, drive it along the body of the device. The arrow should point on the steel object. Having gone a quarter of a turn (conditional on the face of the clock will be 15 minutes), remove the object. The arrow should come to its original position, that is, to point North.
2
Before calculating the azimuthand be sure to check around the compass items of iron, current-carrying conductors or permanent magnets, it may affect the measurements. Then decide the scale of the compass, which measures the degree to which the rotated arrow. Take two neighbors, the numerical values and divide the difference by the number of divisions between them.
3
Install the compass horizontally and remove the limiter from arrow. After several oscillations, the blue arrow end should point North. Set the dial of the compass so that the pointer of the North coincides with the direction of the arrow. This point corresponds to zero azimuth.
4
You can then navigate the terrain. Put in the direction of the object to which the orientation is made thin and long object. This can be a branch, ruler, splinter, match etc. the Only limitation is that the subject should not be made of iron or any alloy of this metal, otherwise the arrow just starts to show on this subject, making it difficult to calculate the azimuth.
5
Calculate the angle between the direction to the object and the direction of the North. To do this, count the number of divisions between them and multiply this number by the scale.

# Advice 2: How to calculate the azimuth

When orienteering is often necessary to move it in the directions specified in advance and not on the sides of the horizon. How this can help us to compass? For movement in the direction you need the ability to calculate the azimuth, i.e. the value that characterizes the angle between the North direction and the direction to the selected landmark.
You will need
• Compass
Instruction
1
Imagine that you are standing in the center of the circle, which is divided into 360 equal parts, and the zero mark is pointing in the North direction. Strokes respectively the other will be sent from the point your location in different directions.
2
Using the counts caused by each stroke, you can specify the direction to any selected as a landmark object on the ground. Assume that the transmission tower is located in front of the bar with a count of 270. This would mean that the object is located from us in the direction that is determined by this count. The angle isexpressed in degrees measured in the direction of clockwise from the North direction to the direction of the predetermined reference point is called the azimuthohms.
3
To determine the azimuthand take up the compass, release the brake of the magnetic needle. Give the compass a strictly horizontal position. After the arrow will cease to oscillate and will rest, align the zero division of the circular scale with the end of the arrow that points North. You have just produced an orienteering compass.
4
Careful now, not to knock the orientation of the compass, rotate the cover so that the front sight was directed toward the selected reference point, and the slot – in your direction. It was necessary to see through the slit and the fly on the landmark. Watch it to the end of the arrow was all the time combined with the zero division. Countdown opposite the pointer (near the fly) will be the numerical expression of the azimuthand the reference point.
5
If you are faced with the inverse problem, i.e. finding the necessary direction on the well-known azimuth, then set the pointer from the fly on equal to the given azimuthat the starting point (e.g., 300 degrees). Now set the compass horizontally and Orient to the North in the way described above. Carefully, trying not to knock out, look at the area through the slit and the fly. On this line choose any point of reference. Direction from your point of standing on the reference point will correspond to the azimuth.

# Advice 3: How to know the azimuth

Everyone at least once in my life had to walk in the woods and think about what to do if you get lost. To navigate the terrain can be different, a lot of ways, the most common are the compass and visible objects surrounding countryside.
Instruction
1
The azimuth is the angle formed between the direction of any visible object area and the direction of the North. The Azimuts is calculated clockwise and the value is from 0 to 360 degrees. To determine the magnetic bearing of the object, take a compass and stand facing the designated object.
2
Put the compass on a horizontal flat surface face up and turn left, then right, until the arrow of the compass the magnetized end will not install in front of the letter S. This is the direction of the North.
3
Now on the glass cover of the compass, place the match so that one end of it passed through the center of the compass, and the other would be focused on selected subject areas. View through the glass on the bottom of the compass and read the number that is under the outer end of a match. This figure shows the value of the azimuth.
4
The azimuth can be determined even on the map. To do this, place the side edge of the card compass, turn the map so that its side edge coincided with the direction of the magnetic compass to the North. The top edge of the card must be on the letter C. Then locate a point on the map which you want to start a movement, join it by a straight line with the object to which you want to come. After you move the compass so that its center was on the point of origin. Hell on the map will be located opposite certain of the numbers on the compass, which will show the azimuth value.
5
The azimuthcalculated from the point of standing in the subject area, known as a direct magnetic azimuth. To find the way back, often using the notion of inverse azimuth that is 180 degrees different from the direct. To determine back azimuth, it is necessary to direct the azimuth, add 180 degrees, if it is less than 180 degrees; or subtract if it is greater than 180 degrees.
Useful advice
It is not recommended to raise the compass to eye level - the measurement accuracy is reduced.
