Some people are surprised to learn that a magnetic compass does not normally point to true north In fact, over most of the Earth, it points at some angle east or west of true (geographic) north The direction in which the compass needle points is referred to as magnetic north, and the angle between magnetic north and the true north direction is called magnetic declination The terms variation, magnetic variation, and compass variation are sometimes used in place of magnetic declination The magnetic declination does not remain constant in time Complex fluid motion in the outer core of the Earth (the molten metallic region that lies from 2,800 to 5,000 km below the Earth s surface) causes the magnetic field to change slowly with time This change is known as secular variation Because of secular variation, declination values shown

on old topographic, marine, and aeronautical charts need to be updated if they are to be used without large errors Unfortunately, the annual change corrections given on most of these maps cannot be applied reliably if the maps are more than a few years old, since the secular variation also changes with time in an unpredictable manner The current year s declination is oftentimes marked in degrees on the map, which is one reason it is important to have a current map Magnetic field models are used to calculate magnetic declination by means of computer programs The user inputs the year, latitude, and longitude, and the program calculates the declination It is possible to use the following web page to calculate declination: http://geomagnrcan gcca/apps/mdcal-engphp (accessed January 08, 2010) This program is able to compute values for any location on the Earth since 1960 Navigating by compass requires determining bearings with respect to true or grid north from a map sheet and converting them to magnetic bearings for use with a compass Important information on the map (see Note 1 on Figure 612, which is showing only a part of the much larger map) is the magnetic declination diagram

Declination diagram will have a star with a straight line representing the North Star (true north) and a line (MN) to the right of it or left of it, depending on the area, to denote the magnetic declination that must be applied for compass correction to use the map for true headings Another line with GN will also appear, which represents the geographic (grid) north, which is used when reading the map An additional note for users (Note 2) is stating that This map is red-light readable, which is typically found on military maps It is important to distinguish between grid north, the direction of reference lines shown on the map, and true north Although declination always refers to the angle between magnetic north and true north, it is often broken into two parts for convenience In order to change magnetic to true headings, we will add east declination and subtract west declination In order to convert from true to magnetic headings, we will subtract east and add west declination In microwave engineering documents, antenna orientation is always given relative to the true north, so it has to be adjusted during the site and path surveys and during equipment installation and alignment 67

Site Surveys
It is recommended that the same company performs site surveys and path surveys because some of the activities overlap and have to be done in a certain sequence For example, establishing the correct and precise coordinates of the sites is the prerequisite for all other activities (including the path design) and should be done only once Coordinates measured by different crews and at slightly different location at the site will create confusion Before visiting a site, the surveyor should perform the following preparations for a site survey:
Become as familiar with the site as possible by studying maps and photos of the site and the surrounding area and sites (called a map study) Find out from the network planner the preliminary positions of the neighboring sites and calculate bearings to the neighboring sites from the site to be surveyed Find out the position of the site, address, directions to the site, and/or coordinates
