Abstract: Requirements have been recently initiated by marine safety; increased liability for offshore marine incidents; and the ever-expanding activity in our already overcrowded harbors, channels, and shipping lanes by both commercial and private boating industries; requirements which have dramatically emphasized the need for an accurate, self-contained all-weather navigational aid. The Ships Acoustic Navigational System (SANS) has been specifically designed to meet many of the system requirements that have evolved from this broad requirement base. There are a number of system features that have been used as the baseline design goals in the development of this new approach to the marine navigational problem. The most pertinent of these features are synopsized as follows: SANS in an all weather marine navigation system, unaffected by the hostile surface enviroment, that can operate day or night. SANS represents a common baseline design concept that is both useful and economic for all vessels, from the sailboat class to the supertanker. SANS can meet the functional navigational requirements for sea lane marking, harbor entrance and terminal approach applications. In the system approach, the emphasis in cost is transferred to a single transmitting station which will service any number of ships/submersibles equipped with an inexpensive receiver. This marine navigation system is self-contained and is categorized as a "no-cooperative." SANS can operate either from cabled shore power or from a self-contained battery pack. The development of SANS was accomplished with these features in mind as priority goals.
