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