We carried on an experiment to obtain the ship's positions with an OMEGA reciever in order to develop an OMEGA simulater. The results were as follows. (1) An OMEGA chart (Fig.3) was calculated by Eq.3. (2) The OMEGA fixes were calculated with Eq.7 to 10. The solutions of these equations converged as shown in Fig.4. (3) The OMEGA track obtained on this experiment was compared with the cross bearing fixes in Fig.5. (4) The OMEGA cocked hats, formed with three lines of ship's position A-C, A-D and C-D, are shown in Fig.6. (5) The OMEGA fixes compared with the cross bearing fixes are shown in Fig.7. (6) The OMEGA positions fixed with A-D pair and C-D pair had the worst acuracy, and the centre positions of cocked hats had the best acuracy. (7) We supposed that the OMEGA fixes deviated to northeastward and southwestward as the acuracies of the position lines of A-D pair and C-D pair were worse than A-C pair.
