Marine Navigation System

Each ship currently uses several navigation equipments, one of which is CMAP Charts for maximum safety.
Today, a ship’s officer has a myriad of marine navigation equipment which makes his life much simpler, thanks to advances in technology. What’s more, today’s seafarers are trained to know the function and operation of all modern navigation equipment which makes sailing smoother and safer.
With modern facilities and automation, a ship today has several sophisticated navigation equipment systems that provide accurate data for shipping.

Previously navigators relied solely on nautical maps, which were actually plotted on paper and were the official databases of the government’s official hydrographic department. These charts are used to provide a two-dimensional view of the seabed or river and its topography to aid safe navigation.

The chart also shows navigation hazards, sudden elevations on the seabed, wrecks blocking navigation channels in confined waters, all kinds of local man-made structures, positions of bridges, ports, buildings onshore, the position of guide buoys, towers, obelisks, and other coastal references. These charts were prepared by the hydrographic department and updated after certain gaps, which made navigation vulnerable to sudden changes in the seafloor of the channel.

A physical chart also uses large blocks of space in the chart space on the bridge where the chart is placed. To avoid this, Electronic Nautical Charts were developed to switch from paper to digital.

All electronic marine charts comply with International Hydrographic Organization guidelines. In addition, these charts are updated regularly in accordance with the resolution adopted by the IMO which invites member governments to conduct hydrographic surveys and publish and disseminate nautical information for safe navigation. Member governments should coordinate among themselves, if necessary, to update information in a timely manner and ensure the greatest uniformity in published charts.

So we see that working graphs with dividers, set-squares, sextants, and other tools have given way to a more digital environment in bridges, almost eliminating the possibility of human error. The bridge’s completely digitally integrated system virtually eliminates the possibility of running aground or getting completely lost at sea.
