There are many electronic aids currently available to assist the navigator in all phases of the voyage of a modern merchant vessel. The three most popular systems for the ocean phase of the voyage are Omega, Loran 'C' and Satellite Navigation. The dilemma which is often experienced is the decision as to which of these systems should be installed on board a particular ship. Quite obviously they all have merits since they are all in current use and the use of all systems continues to increase. In deciding which system is the most suitable for a given vessel on a given route a large number of factors may have to be considered, such as accuracy, coverage, cost, reliability, complexity etc. The purpose of this paper is to examine two of these; accuracy and coverage, since it is this information which is most difficult to gather (to provide a complete picture), both in comparison of systems and in comparison of different manufacturers' equipments.
