Design of Integrated Electronic Chart Pocket Navigator System (PNS) and Application for Passage Ship Auto-track

摘要

With the development of hydrographical work and information techniques, digital charts are more and more popular in maritime applications, and an embedded product—PDA (personal digital assistant) is widely used in navigation for its smallness and portability. However, there is lack of PDA-based product which can provide integrated data management, real-time alternate display and ship auto-track application based on traditional paper chart and s-57 ENC. Aiming at this, some new techniques and algorithms including integrated spatial data management and display mode for ENC and paper chart, multi-scale data organization, embedded chart navigation method based on GPS are presented. And the integrated electronic chart pocket navigator system (PNS) based on PDA was developed.
