Integrated Marine Navigation Systems of the Future

Lee Alexander and Joseph W. Spalding

Abstract:	The marine navigation systems of the future will be significantly different than those presently installed on board most vessels. The advent of NAVSTAR Global Positioning System (GPS), Electronic Chart Display and Information Systems (ECDIS), and Integrated Navigation Systems (INS) represent technological advances of considerable importance to the maritime community. However, it will be the integration of shipboard navigation sensors that offers the greatest potential for significant advances in maritime navigation and safety. This paper reviews technology used in currently-available marine navigation and positioning systems. The discussion covers advances in land-based and satellite radionavigation, automated radar positioning, and integrated primary-secondary positioning systems. Particular focus is made on state-of- technology for GPS and Differential GPS shipboard receivers. Recommendations are provided regarding what improvements are needed in terms of receiver integrity monitoring, azimuth/attitude determination, and fault tolerance necessary to meet the navigation performance requirements for ECDIS and marine INS.
