This was followed by the arduous task of ordering these charts and hoping that they arrive in time.More often than not, this proved a major challenge especially on tramper trades which tend to get last minute voyage orders.A time stamp is printed on the ECDIS screen (see figure below) with both the GPS positions and the LOP.This serves as a ready indication of any offset present between the GPS and Radar fixes. Anti-Grounding Alarms and Settings: Though ECDIS has now evolved into a full-fledged primary source of navigation, it was born as an Anti-Grounding aid to Navigation.Next step is to deselect the Secondary Position Source on the ECDIS as GPS and select Echo Reference in its place.

Once this is done, the user will have to activate the overlay tab of the ECDIS which will super impose the Radar Screen on the ECDIS.However, we all know that GPS signals can be unreliable and are prone to errors occasionally.This problem can be overcome by using the Radar Overlay and Echo Referencing facility in the ECDIS and Radar.Even the dreaded T&P notices are now shown electronically on the ECDIS. Continuous Monitoring of Vessel’s Position: One of the single biggest advantages of the ECDIS over paper charts is its ability to enable the user to see the vessel’s position in real time without user action.The ECDIS is interfaced with both the vessel’s independent GPS transceivers, thereby making the system work even if one fails.
