MASTER-DEQ 10/20 (Electronic Chart Display and Information System - ECDIS)

Electronic Charts and Databases used:
  • Official S-57 Ed. 3.1. (and 3.0) Electronic Navigational Charts manufactured and distributed by Government authorized Hydrographical Offices and provides their continuously electronic online up-dating
  • ARCS Raster Navigational Charts produced by UKHO (British Admiralty)
  • BSB Raster Navigational Charts produced by different authorized organizations in USA and Canada
  • DEM – Digital Elevation Model - from USGS
  • Different proprietary charts and databases (e.g. topographical charts, navigational information and photos produced by MapTech)


The main features of the system:
  • flexible network architecture providing unlimited number of workstations
  • possibility of translation of vessel's position via onboard TV station
  • route planning including voyage planning and route's corridor safety check
  • route monitoring
  • true and relative motion
  • “North Up”, “Head Up” and “Route Up” modes
  • ship's track recording with 10 seconds precision and electronic logbook
  • unlimited number of electronic rulers (ERBL)
  • a large set of different navigational alarms including ECDIS required
  • tide calculation
  • trial manoeuvre
  • RADAR overlay
  • order zones
  • military manoeuvring functions

The system is mounted onboard in special certified hardware (console, computer, monitor...)

The summary number of electronic nautical charts of different formats distributed by NAUDEQ exceeds 5000.
