It is important for users of the Omega navigation syetem to know the optimum LOPs and their accuracies beforehand. This study was carried out to evaluate the accuracies in the western North Pacific area and to propose the recommendable station pairs in these area. Accuracy was evaluated by comparing position fix by the Omega system with those by the cross bearing, radar and the astronomical observation. The recommendable station pairs were selected in considerations of LOP geometry, signal propagation prediction and the accuracy. The following results were obtained: 1. The r.m.s. relative error of the A-C, A-E, C-E combination was 2.0n.m.〜2.8n.m. 2. The r.m.s. relative error of the C-D, D-H, C-H combination was 1.5n.m.〜2.8n.m. 3. The relative accuracy of the automatic receiver using the Pierce skywave correction model was 2n.m.〜3n.m. (r.m.s.).
