Research for Navigation Safety and Function of Electronic Devices on Ship

Abstract

The Marine Radar and use of electronic chart gives precise calculation of range and bearing of targets which is required for accurate navigation. Integration of radar wave detection and ranging system on the navigational station is a mandatory requirement for safe navigation. Human eye alone can guess the distance but cannot quantitatively state the range of object therefore, intervention of RADAR technology makes a ship master accurate object detector. In navigation we can fix vessel’s position by many methods like by cross bearings taken from two different objects, beam bearing to four-point bearing method, Horizontal sextant method, Vertical sextant method, cross bearing from three objects, by celestial fix, by bearing of object and sounding contour change, GPS fixing and by marine Radar. A ship’s master can monitor vessel’s real time position continuously on the ECDIS monitor. All together both equipment have improved master’s ability to better monitoring of navigation.
