Route design and automatic check in electronic chart display and information system

Abstract

For an electronic chart display and information system (ECDIS), the most important function is the route design. In this paper, a novel approach to developing ECDIS was given and then an effective method was proposed for route design and automatic check. The mathematical model and logical relationship for coordinate transformation were also provided. They were adopted in ECDIS developing, which was based on the research of the Vxworks real-time operating system. The actual system application implies that the method is practical and can help navigation very well.
