From January to March in 1984, the phase data of Omega 10.2kHz signals are measured onboard, by a receiver with rubidium atomic standard, along the route between Japan and Western Australia for the purpose of analyzing the signal behavior and evaluating the relative error of LOPs by means of comparing with nominal LOPs (PPC included) by NNSS and Loran-C. Accordingly, recommended LOP combinations along the above route are selected in consideration of the relative accuracies of LOPs and Geometric Dilution of Precision (GDOP). As a result, signal behavior (10.2kHz) of A, G and H are confirmed to be almost the same as described in the Omega Coverage Diagrams. Accuracies of the Omega System are estimated 2〜3 N.M. (RMS) as a whole on the route concerned, but navigators should notice that it is difficult to make good Position Fix in the nighttime at the southern and the eastern parts of the South China Sea because of modal interference on H and G.
