Applications. When using an azimuth, you imagine the point from which the azimuth originates as 2 Draw a line between these points.
Land Nav Task 15 - Determine Azimuths Using a Protractor Bearing can be expressed in milliseconds or degrees, while azimuth can be expressed in degrees frequently, if not always. Next, you will plot an azimuth from a known point on a map. a. Heading is different from course and bearing as it only refers to the direction you are pointing towards. As weve said here many times, land navigation requires as much prep and practice as any other perishable skill. Follow your line outward to the degree scale of your protractor. PRECISION LIGHTWEIGHT GLOBAL POSITIONING SYSTEM RECEIVER, Map Reading and Land Navigation REFERENCES. These cookies will be stored in your browser only with your consent. The conversion (add or subtract) is governed by the direction of the magnetic-north prong relative to that of the north-grid prong. Grid Azimuth Step Action 1 Determine the start point and objective. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. If it is not, then you were plotting in the wrong grid. Determine the grid coordinates to the desired accuracy, for our purposes an eight-digit grid coordinate. For now lets say youre using a USGI Lensatic or other compass that does not have the Declination Adjustment feature. (b) From the base of the grid-north line (prong), draw an arbitrary line (or any azimuth line) at a roughly right angle to north, regardless of the actual value of the azimuth in degrees (Figure 6-9). It also includes some advanced aspects of map reading, such as intersection, resection, modified resection, and polar plots. They use the metric system for measuring distance and feature both . 2. Declination is the angular difference between any two norths. Especially from those who didnt get selected. endstream

Performance Steps On the map, draw a straight line connecting the two points. (4) Convert the magnetic azimuth to grid azimuth. These data are shown in the form of a grid-convergence note. Youve found your location. In some cases, there are no declination conversion notes on the margin of the map; it is necessary to convert from one type of declination to another. 2282 0 obj

(b) To use a magnetic azimuth in the field with a compass, first change the grid azimuth plotted on a map to a magnetic azimuth (Figure 6-11). Identify the map's starting point (A). 4. Location. When using the protractor, the base line is always oriented parallel to a north-south grid line. The North Star (Polaris) and Dubhe, one of . The 0- or 360-degree mark is always toward the top or north on the map and the 90 mark is to the right. Praesidus brings homage to the military watch tradition. The following elements must be present when using polar coordinates (Figure 6-21). 5. The straight edge method is used when a compass is not available. Repeat 3, 4, and 5 for a second position and a third position, if desired.

Locate a point in the distance that can be easily identified on the ground and on the map. This measured angle is the grid azimuth of the drawn line (fig. Place the index of the protractor at the point where the drawn line crosses a vertical (north-south) grid line. Hold your hand at arm's length and close one eye. Your location is where the line on the map crosses the linear feature. Now you must determine the grid azimuthof that linethe angle between the line and grid north. 3. Repeat 3, 4, and 5 for a second position and a third position, if desired. Next: get out the military protractor. Using a protractor, draw a line for the back azimuth on the map from the known position back toward your unknown position. Draw the lines long enough so they both cross.
Figure 6-12. When reading a military map, use the number along the left border of each grid square as your starting point; then read the number along the bottom border. Grid north may be symbolized by the letters GN or the letter y (Figure 6-1). You then should be able to get an eight-digit grid coordinate and find your way to your point. 5. Using a protractor, draw a line for the back azimuth on the map from the known position back toward your unknown position. The direction to the north magnetic pole, as indicated by the north-seeking needle of a magnetic instrument. 2. Grid Azimuth Step Action 1 Determine the start point and objective.

This cookie is set by GDPR Cookie Consent plugin. Draw a straight pencil line between points A and B with the edge of your protractor. If a mistake is made and the reading is taken from the ending point, the grid azimuth will be opposite, thus causing the user to go in the wrong direction. Directions are expressed as units of angular measure. In the jpg below, you can see the declination window at 6 oclock on the compass, or specifically, at Zero degrees. But also remember, that youll be only asked to pass the same course that thousands of other candidates have passed before you. 2 Draw a line between these points. For mils, if the azimuth is less than 3200mils, add 3200 mils, if the azimuth is more than 3200 mils, subtract 3200 mils. Ensure this line is at least two inches long to facilitate use of the protractor. Determine the value of the angle (grid azimuth) from the scale. Mark . For bearings of 181 to 359 degrees, rotate the bezel clockwise.
The degree scale is graduated from 0 to 360 degrees; each tick mark on the degree scale represents one degree. The azimuth angle is like a compass direction with North = 0 and South = 180.

Using the laser range finder to determine the range enhances your accuracy in determining the unknown positions location. The military protractor, GTA 5-2-12, contains two scales: one in degrees (inner scale) and one in mils (outer scale). Theyre not essential for shooting an azimuth or bearing (from hear on out referred to as either a Grid Azimuth (GAZ) or Magnetic Azimuth (MAZ)), but they are very, very useful is plotting (determining) positions on a map to within various levels of accuracy (read distance from the actual object being plotted). To do so the successful navigator must follow these steps: This one sounds more difficult than what it truly is.
