SummaryThis article examines the practical application of formulae for computing long lines on the ellipsoid. The main aim is to eliminate the successive approximation generally required. For the inverse problem, this is achieved by the method ofE. M. Sodano, Army Map Service, U.S.A. An adaptation of a method produced byG. T. McCaw is used for the direct problem.Results are given of five practical examples, including two which extend halfway round the world. Construction of further special…

This paper gives compact formulae for the direct and inverse solutions of geodesics of any length. Existing formulae bave been recast for efficient programming to conserve space and reduce execution
An Algorithm for the Inverse Solution of Geodesic Sailing without Auxiliary Sphere
An innovative algorithm to determine the inverse solution of a geodesic with the vertex or Clairaut constant located between two points on a spheroid is presented. This solution to the inverse
Solving the Direct and Inverse Geodetic Problems on the Ellipsoid by Numerical Integration
Taking advantage of numerical integration, we solve the direct and inverse geodetic problems on the ellipsoid. In general, the solutions are composed of a strict solution for the sphere plus a
Validation of Vincenty's Formulas for the Geodesic Using a New Fourth-Order Extension of Kivioja's Formula
Vincenty’s (1975) formulas for the direct and inverse geodetic problems (i.e., in relation to the geodesic) have been verified by comparing them with a new formula developed by adapting a
A rigorous non-iterative procedure for rapid inverse solution of very long geodesics
The purpose of this paper is to unify, under a single cover, the many theoretical and practical aspects of a rigorous, yet rapid, non-iterative procedure for the inverse solution of very long
The computation of long geodesics on the ellipsoid by non-series expanding procedure
In this paper the author shows a procedure to settle the computation of very long geodesic lines on the ellipsoid without using the series expansion. The integration of elliptic integrals appearing
Solutions to the ellipsoidal Clairaut constant and the inverse geodetic problem by numerical integration
Abstract We derive computational formulas for determining the Clairaut constant, i.e. the cosine of the maximum latitude of the geodesic arc, from two given points on the oblate ellipsoid of
Numerical determination of the geodesic curves: the solution of a two-point boundary value problem
In this paper, we suggest a simple iterative method to find the geodesic path on a surface parameterized byorthogonal curvilinear system between two given points based on solving Boundary Value
A Novel Approach to Loxodrome (Rhumb Line), Orthodrome (Great Circle) and Geodesic Line in ECDIS and Navigation in General
The navigation based on geodesic lines and connected software of the ship’s devices (electronic chart, positioning and steering systems) gives a strong argument to research and use geodesIC-based methods for calculations instead of the loxodromic trajectories in general.

It is concluded that a complete, stable, precise, accurate and fast solution of the problem in Cartesian coordinates is accomplished.


AbstractThe use of radar has already begun to revolutionise the science of surveying. It requires the computation of lines on the earth between a hundred and a thousand miles long for the fixation of
