Part 3 Vincenty's Formulae

    Note This implementation of Vincenty's Direct Formulae uses the parameters {a, f1, b} from the GRS80 ellipsoid as referenced by the Geocentric Datum of Australia 1994 (GDA94).

    1.  In calculating (lmn,Lmn):

lt  :  is the latitude of the fixed transmitter (decimal radians)

Lt  :  is the longitude of the fixed transmitter (decimal radians)

α   :  is the azimuth angle (decimal radians)

d   :  is the separation distance to required point (m×100 metres)

a   :  is the semi-major axis with value 6378137 metres

fl  :  is the flattening of the value 1/298.25722210

b   :  is the semi-minor axis of (a×(1-fl))

    2. Using an initial value, iterate the following three equations until the change in ϕ is less than 10-12.

    3. Then:

    Note use the four-quadrant inverse tangent, atan2.

    Note use the four-quadrant inverse tangent, atan2.
