Descripción de Variation

VARIATION for the current day.

Used in navigation with a magnetic compass.

-

Variation is the angle between the magnetic and geographic meridians at any place, expressed in degrees east or west to indicate the direction of magnetic north from true north. Called MAGNETIC VARIATION when a distinction is needed to prevent possible ambiguity. Also called MAGNETIC DECLINATION. (Bowditch)


The app uses the World Magnetic Model: WMM2020.

The new model is valid from 10/12/ 2019 through 31/12/2024.

See: https://www.ngdc.noaa.gov/geomag/WMM/DoDWMM.shtml


Your last position is automatically saved.

- Storage permission needed for Google Maps cache and for save your position.


COURSE CALCULATOR

Compass and true course.

DEVIATION COEFFICIENTS

Dev = A + B SIN(Ra) + C COS(Ra) + D SIN(2Ra) + E COS(2Ra)

Calculate the coefficients A,B,C,D,E with "Magnetic compass" Windows application, (available at Navigational Algorithms website).

Enter them and save. The App will read the data and Course calculator will be able to compute the deviation.
