Why Do The Ship’s Navigators Depend On Microwaves?

Ship's Navigator System

Microwaves are a kind of radiation. They can easily pass though things that would block ordinary radio waves like rains and fog. Microwaves can also be focused and sent in a narrow beam, which helps in transmitting radio waves over long distances.

These microwaves are used by ships for navigation purposes. All ships have a radar screen, which uses microwave radiation to detect distant objects. The microwaves scan round in a circle and the echoes sent back produce an image on the screen, and it used for the Ship’s Navigators.


Below Navigator Info from Wikipedia (

A navigator is the person on board a ship or aircraft responsible for its navigation. The navigator's primary responsibility is to be aware of ship or aircraft position at all times. Responsibilities include planning the journey, advising the Captain or aircraft Commander of estimated timing to destinations while en route, and ensuring hazards are avoided. The navigator is in charge of maintaining the aircraft or ship's nautical charts, nautical publications, and navigational equipment, and generally has responsibility for meteorological equipment and communications.
