Loxodrome Navigation: Distance and Course

(Loxodrome Navigation is same as Mercator Navigation)

Calculate loxodrome distance and constant true heading (course) from origin to destination.
(using reference ellipsoid datum WGS84.Course is exact, but distance is spherical)

Geographic Coordinates of ORIGIN

deg min sec or deg min.ddddd or deg.ddddddd
LATITUDE
Deg Min Sec

LONGITUDE
Deg Min Sec

Geographic Coordinates of DESTINATION

deg min sec or deg min.ddddd or deg.ddddddd

Click on Button:

Loxodrome Distance from ORIGIN to DESTINATION is: nautical miles (not exact)

Constant True Heading (Course) from ORIGIN to DESTINATION is: degrees
degrees minutes seconds

True Heading (Course) = 0 or 360 is to the North Pole, not to the Magnetic North
North = 0 East= 90 South = 180 West= 270
