You can use the Java Geodesy Library for GPS, it uses the Vincenty's formulae which takes account of the earths surface curvature. m12 (m) = S12 (m^2) =. Finally, we used the most accurate Vincenty’s formula. Returns the lat and long of projected point and reverse azimuth. In order to maintain a straight path (the definition of a geodesic), the path must bend away from the circle of latitude (unless it's the equator). α1 = atan (cos U2 · sin λ / cos U1 · sin U2 − sin U1 · cos U2 · cos λ) which I presumed could be converted to degrees and normalised by mod (a, 360). This Equilibrium Price and. lats, longs and azimuths are passed in decimal degrees. It then uses the haversine formula to. Tap for more steps. The accuracy of Vincenty's formulas is about 0. where, r depicts the earth’s radius, a and b depict the latitude . D. According to the formula for sin2u, the values sinu and cosu must be known.
