P olar Navigation Method Based on P olar Stereographic P rojection
摘要
Abstract
The global climate is getting warmer and warmer, the arctic ice cover is melting more quickly which enable the whole line navigation of arctic channel in summer, the rapid convergence of geographic meridians in arctic makes the naviga⁃tion error of the traditional navigation method based on the geographic coordinate system too strong to use. In view of the a⁃bove⁃mentioned facts, the polar navigation is researched in this paper, the problem of using in arctic of the conventional chart and the traditional navigation method is analysed firstly, the polar grid coordinate representation based on the polar stereographic projection is represented, the conversion relationship between the geographical coordinates and the grid coordi⁃nates based on the polar stereographic projection is derived, the method represented in this paper can provide a precise posi⁃tion on earth for the polar navigation, and it is convenient for polar maritime jobs.关键词
