(Figure 071-COM-0018 1) Note: When measuring azimuths on a map, remember that you are measuring from a starting point to an ending point. 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. Determine the grid coordinates to the desired accuracy. If youre not certain of your exact location but are located on a linear terrain feature such as a road, creek or along a similar body of water, this can pinpoint your position. how to determine grid azimuth using a protractor Land Nav Task 15 - Determine Azimuths Using a Protractor Because you use north (0 or 360 degrees) as your base line, 270 degrees away from north will always be due west. Back azimuths are calculated as follows: If the original azimuth is less than 180 degrees you ADD 180 degrees to the original azimuth, thus an azimuth of 45 degrees (<180) will have a back azimuth of 225 degrees. With North = 0 and South = 180, the azimuth angle is similar to a compass direction. The terms azimuth and direction are interchangeable. Figure 6-15.

Converting azimuths to quadrant bearings or vice versa is easy. The G-M angle value is the angular size that exists between grid north and magnetic north. A straight line to the azimuth point is the angle between the central meridian or a line parallel to it at a given point in the plane of a rectangular coordinate system. The straight edge method is used when a compass is not available. More on that in the future. Determining a Grid Azimuth Using a Protractor There are two ways you can determine an azimuth.

Thats why it is imperative for all of the candidates to learn the basics of land navigation to the point where you could teach a class on any of it, keep a cool head and prepare. To determine your GAZ, you should use one of these, known as a 'protractor.' Using it is pretty simple: Place the center over the point on the map you're using to determine which azimuth you're going to travel on, square the protractor to the map's grid, place a small tick mark in the center of the protractor (they usually have a hole . Military personnel need a way of expressing direction that is accurate, is adaptable to any part of the world, and has a common unit of measure. The azimuth angle is the direction from which sunlight enters the compass. ^ni`H2pI35%S8lKXoboAJXT/k]3 @[J Since 0 degree is the same as 360 degrees, then 2 degrees is the same as 362 degrees.
