Navigation techniques have evolved over the years, and sailors now have access to advanced navigation equipment that makes navigation easier and safer.

Radio aids to navigation are radio signals transmitted from fixed stations that provide navigational information to vessels at sea. There are different types of radio aids to navigation, such as radio beacons, radio direction finders, and radar beacons. Radio beacons transmit radio signals that can be used to determine a ship’s position, while radio direction finders are used to determine the direction of the signal.

Satellite navigation systems are navigation systems that use satellite signals to determine a ship’s position. These systems are highly accurate and reliable, and they have become the preferred navigation system for many sailors. The Global Positioning System (GPS) is the most well-known satellite navigation system, and it is used by ships all over the world.

Legal Time

Legal time is the time that is used as the standard time in a country. It is the time that is used to regulate activities such as air traffic, shipping, and international trade. The legal time is determined by the local government, and it is usually based on the time at the capital city.

Radio Time Signal

Radio time signals are signals transmitted by radio stations that provide accurate time information. These signals are used by ships to set their clocks and ensure that they are operating on the correct time. The most well-known radio time signal is the Greenwich Mean Time (GMT) signal.

Electronic Position Fixing Systems

Electronic position fixing systems are systems that use electronic equipment to determine a ship’s position. These systems are highly accurate and can provide a ship’s position within a few meters. Electronic position fixing systems are essential for navigating in areas with restricted visibility, such as in fog or heavy rain.
