Abstract: NORWAY HAS LONG TRADITIONS in the field of navigation for fisheries and merchant marine use. Recently the whole navigation aid situation in Norwegian waters was extensively studied and analysed by a government nominated committee. This analysis concluded with what may be called a national navigation aids plan for Norway. Although this plan is predicted in specific conditions, some of the experiences gained during the implementation of the plan may be of general interest. Complete Decca Navigator coverage of the Norwegian coast was achieved on the 14th of iVIay when H. M. King Olav inaugurated the last four chains. Now t’ransmitting equipment is developed for ml-manned (automatic) operation. Results so far are satisfactory and gives better coverage in narrow fjords than expected. The CONSOL system with longer range and lower accuracy need no special receiver and is therefore inexpensive to use. Three stations around the Norwegian Sea, sharing one frequency, are now under construction. Standardization of nav. aid systems may be a benefit, but overall economy best served if the large number of users can choose a system to fit their needs. For merchant marine world wide use the OMEGA system seems to hold the best promise not withstanding recent developments in satellite and inertial navigation.
