An algorithm for determination of geodetic path for application in long-range acoustic propagation

Abstract

A computer program has been developed for the construction of geodetic path between two points on the spheroidal surface for application in long range acoustic propagation in the ocean. Geodetic equations have integrated numerically upto the distance of interest subject to initial conditions and a azimuth (forward problem). Inverse problem has been solved interatively based on the spheroidal geometry to supplement the initial conditions to the forward problem. The algorithm has been test validated. Program listing along with sample output is also appended
