True Rhumbline Distance (WGS-84) Calculations Laptev Sea ​​​High quality diagrams and photographyIn 2000 Dr Tijardovi published the article Rhumbline Distances in Journal of Navigation, Cambridge after conducting a large research project on GPS accuracy where he found out that none of 25 GPS receivers calculated accurate distance. In 2004, Brown's Nautical Almanac introduced True Rhumbline Distance and since then Transas ECDIS and Admiralty Navpac IV have been using True Rhumbline Distances in their software. The only way to get the accurate
