26 maj 2024 · Our calculator will help you find the magnetic declination for your specific location and date. A positive declination (+D) means that your compass will point east of north. A negative declination (-D) means that your compass will point west of north.
Calculate magnetic declination easily with our Magnetic Declination Calculator. Get accurate results for your location and improve navigation for hiking, camping, and outdoor activities. Use our free online tool to find magnetic variation and enhance your compass readings today!
For this calculator you enter the co-ordinates (latitude and longitude) of your site in degrees, minutes and seconds and it will instantly convert them to eastings and northings expressed in TM grid references. They are then in the form required by GetDec. The programme will then tell you not only the sun’s “apparent declination” but also the
MagDec is a graphical front end for the NCEI online Magnetic Field Calculators that eliminates the need to input geodetic coordinates and displays the calculated magnetic declination and secular variation in a placemark balloon. Position the point of interest (POI) in the center of the view.
2 lip 2022 · Use the tool below to compute values for the geomagnetic field and secular variation for a given set of coordinates and date. This calculator uses the World Magnetic Model as released in Dec 2019.
Compass, magnetic and true course calculator. Calculates true, magnetic and compass direction (course, bearing) by a given direction, magnetic declination and deviation.
Magnetic declination also undergoes changes that are much more rapid than secular variation and are a result of magnetic activity. These variations can be smooth and cyclic, with amplitudes of several minutes of arc in southern Canada, or, during magnetic storms, large and erratic.
