Celestial navigation course for beginners. Voyage planning/passage planning tool. Single rhumb line and great circle calculations on an ellipsoid.
composite sailing. 1204. Rhumb Lines A rhumb line makes the same angle with all meridians it crosses and appears as a straight line on a Mercator chart. The principal advantage of a rhumb line is that it maintains 1. latitude.
Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.
Rhumb Line Sailing: Calculation. First loxodromic problem: Departure position P1 (φ1, λ1) to the arrival position of P2 (φ2, λ2). Unknown are the navigation course (Kl) and loxodromic distance (Dl). Δλ = (λ2 – λ1) – relative coordinate, the difference of longitudes. ΔφM = (φM2 – φM1) – relative coordinate, the difference of Mercator’s widths.
