DGNSS / DMB NAVIGATION SYSTEM FOR SHIP

摘要

The present invention relates to a DGNSS/DMB navigation system for a marine vessel, capable of enabling safe sailing by providing real time traffic information for safe sailing and DGNSS correction information to a marine user through a digital multimedia broadcasting (DMB) data channel and making the marine user output the information. The DGNSS/DMB navigation system includes: a DGNSS/DMB management system (80) broadcasting DMB data including marine traffic safety information including the DGNSS correction information; a DMB relay (40) receiving the DMB data and then modulating and converting the DMB data into an RF channel to deliver the channel to a corresponding zone; and a vessel terminal (30) receiving a GNSS signal and the DMB data from the DMB relay (40), calculating a correction position by using the GNSS signal and the DGNSS correction information, included in the DMB data, and outputting navigation signal reliability information and the marine traffic safety information to an electronic nautical chart (ENC).
