In the United States, Statute 14 USC 81 assigns responsibility for aids to navigation to the U.S. Coast Guard. Established aids provide the user with position determination capabilities--to avoid hazards, reach destination or to maintain a fixed location. The maritime environment is divided into the high seas, the coastal/confluence zone (CCZ), and the harbor/harbor entrance zone (HHE). The major unsatisfied area is the coastal confluence zone and the Department of Transportation (DOT) has recommended that this zone be given priority consideration by providing it an adequate radio navigation aid system. Taking into account accuracy, coverage, operating experience, availability of equipment and cost, it has been proposed that Loran-C be the designated system. A portion of the system is already in existence and will remain so for considerable time is response to Department of Defense (DOD) requirements. Installation of Loran-C to cover the entire Coastal Confluence Zone and the Great Lakes, will enable U.S. Government funding of the existing Loran-A System to be phased out in a reasonable length of time.
