When using the protractor, the base line is always oriented parallel to a north-south grid line. Step 2. Is it easy to get an internship at Microsoft? Land Navigation - PowerPoint PPT Presentation - PowerShow Without moving your protractor, take a pencil and find the corresponding north/south minor gridline by using the vertical side of the triangle. True north is usually represented by a star (Figure 6-1). Your squad leader can show you exactly how to use the protractor. On medium-scale maps, the declination information is shown by a note in the map margin. They are scaled to the Military Grid Reference System (MGRS). In laymans terms, if you arent sure exactly where you are at and need to pinpoint your location and can see two or more distant points that are recognizable on your map sheet, you can shoot an azimuth to them and determine the back azimuth from those points to pinpoint your location. The angle between grids is measured using a protractor. Read 0 degree on the top to this north-south grid line, and read 180 degree at the bottom to the same grid line. To get the most production out of your array, this article explains how to find the correct tilt and azimuth angle. Using your pencil, make a small tick mark on the map at the edge of the protractor at the desired azimuth. The north that is established by using the vertical grid lines on the map.

What will you use to find the grid azimuth between two plotted points on a map? Azimuth and Back Azimuth To do this, you must take a back azimuth. (b) To use a magnetic azimuth in the field with a compass, change the grid azimuth plotted on a map to a magnetic azimuth (Figure 6-14). Converting to a grid azimuth when the G-M angle is greater. Protractor Note: The grid azimuth is the degrees/mils value where the azimuth line crosses the protractor scale. Orient the map using a compass and/or by terrain association. Turn your entire body as a unit until your predetermined azimuth falls under the fixed black index line. 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. The protractor will be used to measure the angle between the horizon and the distant object, this is also called the altitude. (3) Lay a straightedge on the map using a known position as a pivot point. Follow the lines to where they intersect.

Standards: Identify the starting point and ending point on the map, draw a straight line on the map connecting the points, align the protractor to the map, and determine the value of the angle. For now lets say youre using a USGI Lensatic or other compass that does not have the Declination Adjustment feature. eQK/E!),HZ7^}-9mPkB"SJBvU[O7$L&Wq3/CPV-u9Ik0j^fIJ2Aryb:m=^N DK|cE< (2) Locate and mark your position on the map. Remember, any of these exercises that you arent entirely sure of conducting properly can be done with any map, compass, and protractor. f. The location of the user is where the line crosses the linear feature. Because there are 360 degrees in the azimuth circle, the opposite direction would be 180 degrees from the azimuth (half of 360 degrees). Read the value of the angle from the protractor. A visualization depicting the Soldiers Manual of Common Tasks (STP 21-1-SMCT) task Determine Grid Azimuths Using a Protractor (071-COM-0018). Screaming Death Habitat Trainable Appearance Size In the same vein, how big is the, When youre in doubt, dont use your horn unless its absolutely necessary to keep yourself safe. a. A back azimuth is a projectile of the azimuth from the origin to the opposing side of the azimuth circle. Step 2: Rotate the protractor so that it is aligned with the north reference lines on your map. Overview of Navigation in the Military (land NAV and more) The coordinate scale and protractor is a square piece of clear, thin plasticcalled a "protractor" for short. It does not store any personal data. Identify the starting point (A) on the map. Determine the value of the angle (grid azimuth) from the scale. Count the number of degrees from the 0-degree mark at the top of the protractor to this north-south grid line and then count the number of degrees from the 180-degree mark at the bottom of the protractor to this same grid line. Grid north may be symbolized by the letters GN or the letter y (Figure 6-1). Using the edge of your protractor, draw a straight pencil line between points A and B. How to Read the Military Protractor - cyanavigation.com Simply refer to the conversion notes that appear in conjunction with the diagram explaining the use of the G-M angle (Figure 6-8).
