Headway Electronic Chart Display and Information System

Electronic Chart Display and Information System – ECDIS

The system is able to combine with AIS, GPS, ARPA, Gyro Compass, Speed Log, Echo Sounder, Autopilot and other communication and navigation equipment. It has the capability to deal with varieties of information, including maritime geography, sailing states of this vessel, navigation environment and massive numbers of vessels. It provides navigation, collision-avoidance assistance and route management of vessels. It can be used in a variety of large and medium sized vessels.

Chart Support

Compatible with C-MAP chart and S57 / S63 Standards.

Multiple Functions

  • Auxiliary Navigation

    Multiple information can be processed simultaneously including speed logs, compass and GPS positioning to achieve the best positioning, track, heading and speed.

    Real time search of various information of the surrounding vessel that can provide more accurate acoustic and light alarm to prevent collision.

  • Object Collision Avoidance Alarm

    The system can combine AIS and APRA to achieve Collision Avoidance Assistance. It is able to monitor the current vessel in relation with other vessel’s planned routing and automatically calculate the deviation as necessary and activate the alarms.

    The system is also able to detect hazardous area, reef, restricted navigation areas and shoal.

  • Navigation Administration

    ECDIS is also able to perform route planning and management with a automatic log recording function. It is able to capture detailed information of the objects, navigational condition, current, weather condition and vessel’s performance.

    ECDIS is also able to check local and destination’s tidal condition. Using the information collected, EDIS is able to pre-plan an alternative route.
