SAINT MARYS RIVER COGLAD NAVIGATION SYSTEM

A short baseline Loran-C (mini-Loran) chain has been installed by the Coast Guard to facilitate ore-boat traffic between Lake Superior and Lake Huron via the St. Marys River. A Coast Guard Loran Assist Device (COGLAD), was modified for shipboard evaluation aboard Coast Guard vessels on the St. Marys River. This report discusses the COGLAD hardware and software modifications, way-point survey data, operating procedure, test results, and recommendations.
