E-Navigation을 위한 항만 항법체계 설계에 관한 연구

Abstract

With the advent of Electronic Chart Display and Information Systems(ECDIS) and Automatic Identification Systems (AIS) as the principal navigation equipment of E-navigation strategy, mariners will begin to practice “e-navigation\\\\\\\\\\\\\\\\' and increasingly rely upon these systems to navigate safely and efficiently. However, these electronic systems require \\\\\\\\\\\\\\\\'e-inputs\\\\\\\\\\\\\\\\' in order to function. At present, the choices for e-input are limited, and they are installation dependent. This means that the mariner must be suitably equipped in order to use an alternative e-input. If the primary e-input is lost, and the vessel is not equipped to make use of suitable alternative e-inputs, then continued operations will have to be done the \\\\\\\\\\\\\\\\'old fashioned way\\\\\\\\\\\\\\\\' using conventional navigation. The final objective is a recommendation of dual harbor positioning system on the most appropriate mix of positioning systems to satisfy the marine needs for radionavigation, positioning services.
