Align a protractor (left drawing) or the N-S or E-W directional axis of a compass (right drawing) with the map's border and read the bearing in degrees toward the direction of the destination. c. Grid North. Using your pencil, make a small tick mark on the map at the edge of the protractor at the desired azimuth. For your convenience, you can use a UTM Universal Transverse Mercator AKA USGS 7.5 minute map. A protractor is the most accurate way to determine a grid azimuth . c. Grid Convergence. (d) Read the value of the angle from the scale; this is the grid azimuth from point A to point B (Figure 6-4). True north is usually represented by a star (Figure 6-1). Mark . What will you use to find the grid azimuth between two plotted points (1) With Notes. A line from 0 to 180 degrees is called the base line of the protractor. Figure 6-7. It also may be convenient to construct a G-M angle conversion table on the margin of the map. of the angle from the protractor. Determining a Grid Azimuth Using a Protractor There are two ways you can determine an azimuth. 2023 The SOFREP Media Group. First: plot a line from Point A (your position) to Point B (Thy Fair Maiden). Azimuths are also called a whole circle bearing system (W.C.B). 2. There are 180 140 = 40 degrees between the South and the point, therefore the quadrant bearing is S40E. This circle is divided into 360 degrees or 6400 mils (Appendix G). Underneath the compass is a small standard screw slot that an accompanying tool will adjust to whatever your declination is, East or West. endobj By clicking Accept All, you consent to the use of ALL the cookies.

This value will be written in the map margin (in both degrees and mils) beside the diagram. It alters the function of your joystick: DP, How big is the whispering death in a Boulder Class dragon? Ninety degrees corresponds to east, 180 degrees is south, 270 degrees is west, and 360 degrees and 0 degrees mark north. c. To obtain an accurate reading with the protractor (to the nearest degree or 10 mils), there are two techniques to check that the base line of the protractor is parallel to a north-south grid line. How do you calculate the azimuth of a line? This value is expressed to the nearest 1/2 degree, with mil equivalents shown to the nearest 10 mils. The azimuth angle is the compass direction from which the sunlight is coming. How to calculate the azimuth of a grid?

When an azimuth is plotted on a map between point A (starting point) and point B (ending point), the points are joined together by a straight line. You use the right stick to press it. a. Determine the grid coordinates to the desired accuracy. (1) Plot two eight digit grid coordinates. Simply refer to the conversion notes that appear in conjunction with the diagram explaining the use of the G-M angle (Figure 6-8). Convert the grid azimuth to a back azimuth. The GMA on a map from 2004 is 2 degrees 17 minutes. The protractor will be used to measure the angle between the horizon and the distant object, this is also called the altitude. Other authors use a variety of slightly different definitions (i.e., angles of 180 and South = 0). e. Convert the grid azimuth to a back azimuth. The horizontal coordinate system, also known as the Alt/Az system, is a method for describing the exact position of objects in the sky, such as planets, the Sun, or the Moon.

Determine the magnetic azimuth from your location to the distant known point. Next, you will plot an azimuth from a known point on a map. When using the straightedge method (Figure 6-19). A star 45 degrees east of due north, for example, has an azimuth of 45 degrees. None of your azimuths need conversion until such time as you use a different compass one that cant be adjusted similarly. Draw a line along the straightedge away from the known position on the ground toward your position. The conversion (add or subtract) is governed by the direction of the magnetic-north prong relative to that of the north-grid prong. The angle between grids is measured using a protractor. PO Box 1077 MURFREESBORO, Tennessee 37133 United States, P.O. Azimuth and Back Azimuth Their horizontal facing in relation to the Equator is known as the Azimuth angle. To maximize the output of solar panels, they should face directly into the sun. How to measure the performance of an azimuth? Magnetic readings are obtained with magnetic instruments, such as lensatic and M2 compasses. Using the scale, determine the angle (grid azimuth). The azimuth of the grid is defined. Orient the map using a compass and/or by terrain association. It's best to draw the line past both points to make it easier to determine the degree of your azimuth. Which is the military protractor GTA 5-2-12? mark on the protractor and read to the right (clockwise) until you reach the point where the azimuth line crosses the scale (s) of the protractor. Susan is 20 degrees off course. Resection with map and compass. 5-29). There are three base directions or azimuths: true, grid, and magnetic. Photos courtesy of Army Study Guide, author, DOD. 124. 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). When using an azimuth, you imagine the point from which the azimuth originates as Course Hero is not sponsored or endorsed by any college or university. (5) Repeat the above steps at position (B) and check for accuracy. Now you must determine the grid azimuthof that linethe angle between the line and grid north.

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. Personally, I prefer maps that use the MGRS (Military Grid Reference System) which is similar to the UTM, but scaled in 1:25,000 & 1:50,000, which is what I learned in during active duty. Identify the map's starting point (A). 6. Refer to Chapter 9, paragraph 4, for details. The sun is always directly south in the northern and directly north in the southern hemisphere at solar noon. 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. 1. Convert the grid azimuth to a back azimuth. The intersection of the lines is your location. Identify the map's end point (B). This is because 2 degrees and 362 degrees are located at the same point on the azimuth circle. 7i To determine azimuth, how do you use a protractor? At the end this half-hour training, you will be able to, determine a grid azimuth using a protractor. PDF Topic 6 Angle Measurement Intersection And Resection In the jpg below, you can see the declination window at 6 oclock on the compass, or specifically, at Zero degrees. An azimuth is the direction measured in degrees clockwise from north on an azimuth circle. Place your protractor on the map with the index mark at the center of the known point and the base line parallel to a vertical, north-south grid line.
