Aerospace Instrument-Making Annotation << Back ANALYTICAL SOLUTION OF THE NAVIGATIONAL PROBLEM ON THE ORTHODROME IN GEOCENTRIC COORDINATE SYSTEM S.V. Sokolov, P.A. Kuсherenko, A.A. Bayandurova The navigational problem solution for the objects on the orthodromic trajectory is obtained for geocentric coordinates. The possibilities of its application for improving the accuracy of the mobile objects navigation and computational resources reducing are demonstrated. Key words: navigational systems, orthodromic trajectory, geocentric coordinate system, navigational problem analytical solution.
