摘要
Abstract
The convergence of the geographic meridians to the pole in Arctic makes obtaining essential navigation infor‐mation difficult when in polar regions ( especially near the poles ) using conventional INS mechanization which uses meridians as heading reference and expresses positions as longitude and latitude coordinates .Given this ,transverse terrestrial coordi‐nate system is established ,and false graticules is constructed .Transformational relationship between transverse coordinate systems and conventional coordinate systems as well as parameters of direction and fixing is deduced .In the end ,it puts for‐ward and designs INS mechanization in Arctic which uses quaternion as ship attitude ,expresses ship position as transverse terrestrial orthogonal coordinate and selects transverse geographic coordinate system as its navigation system .关键词
