Abstract
This report is a description of a method of solution for obtaining ship's sailing parameters (latitude, longitude, speed, course) and sky wave correction from Loran data. It consist of applying successive differential corrections, obtained by a least squares treatment, to a set of initial approximations for the ship's sailing parameters and sky wave correction. Chapter 4 presents the results when the method of solution was applied to Loran measurements of T.U.M.M. Training Ship Shioji Maru on 23rd of July 1974. The parameters, which were determined, agree very well with those published by cross bearings and radar. The computed height of reflection of wave of frequency 100kHz, have been obtained with this experiment, was about 66.5km and the angle of incidence was about 81.5 degree.
