The Rhumb Line Formulas. With the next diagram, we expand on the work above: The rhumb line AZ is divided into a large number of equal parts AB, BC, CD, DZ. aB, bC, cD… are arcs of parallels of latitude drawn through B, C, D….. Pa’, Pb’, Pc’… are meridians of longitude. Therefore, the angles at a, b, c….. are right angles.
The question we ask affects the range and point in applying the loxodrome (rhumb line) in case the ECDIS equipped with the great circle (great ellipse) approximation algorithms of given accuracy replaces the traditional nautical charts based on Mercator projection.
Using two different examples, this video shows how to calculate the course and distance between two positions; and how to calculate the position arrived if d...
Rhumbline Sailing (RLS ) The proposed formulas for rhumbline sailing calculations on the ellipsoid solve both the direct and the inverse RLS problem. In traditional navigation the navigator is interested only in the inverse RLS problem that solves for the “course to steer” and the “sailing distance” from one location to another.
Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.
Proposals of algorithms for solving Navigation faculty’s problems regarding navigation along rhumb line (loxodrome), for officer trainees and civil students of Faculty of Navigation and Naval Weapons and for deck seamen on operational level, are presented in this paper.
In navigation, a rhumb line, rhumb (/ r ʌ m /), or loxodrome is an arc crossing all meridians of longitude at the same angle, that is, a path with constant bearing as measured relative to true north.
