SHIPBOARD AREA NAVIGATION AND GUIDANCE SYSTEMS USING LORAN-C

The Applied Physics Laboratory (APL) of Johns Hopkins University, under contract by the U. S. Coast Guard, recently developed two Loran-C area navigation/guidance systems for shipboard use. The two systems, COGLAD and C-LAD, are presently undergoing extensive testing aboard Coast Guard cutters along the east coast of the United States. COGLAD was developed primarily to prove the feasibility of precisely guiding a vessel through restricted waterways in real-time and to allow for accurate positioning of navigational aids when visual references are not available. C-LAD is a less complex, inexpensive version of COGLAD designed for large quantity production. This paper deals with the development and field tests of COGLAD and C-LAD. Proposed applications of the equipment are discussed and related to design capabilities and measured performance. A short discussion of recently developed low-cost Loran-C receivers is included since they form a part of the complete system.
