Learn about the history and types of navigational instruments used by nautical navigators and pilots. Find out how charts, dividers, sextants, compasses, chronometers, and electronic aids help to determine position, speed, direction, and time.
- Gyro Compass. It is used for finding the right direction. Unlike magnetic compass, gyro compass is not hampered by an external magnetic field. It is used to find the correct North Position, which is also the earth’s rotational axis to provide a stable directional source.
- Radar. The seagoing vessels depend on S-band and X-band frequency radar system for navigation as it can detect targets and display the information on the screen such as the distance of the ship from land, any floating objects (an island, rocks, iceberg etc.)
- Magnetic Compass. The magnetic compass work in conjunction with the magnetic field of the earth and is the essential means of the direction indicating device.
- Auto Pilot. The ship bridge layout is filled with equipment and tools used for navigation. The autopilot is considered to be one of the most effective bridge navigational equipment as it assists the human operator in controlling the ship by keeping the steering in autopilot, which allows them to concentrate on broad aspects of the operation.
Learn about the ancient navigation tools that sailors and explorers used to find their way across the land and sea. From maps and landmarks to compasses and astrolabes, discover how these instruments evolved over time and how they are still used today.
- ARPA. An ARPA or an Automatic Radar Plotting Aid is a system that is used for creating tracks with the use of radar contacts. This system can calculate the course, speed and the closest point of approach (CPA) of a tracked object.
- ATA. An ATA or an Automatic Tracking Aid is quite similar to an Automatic Radar Plotting Aid. This navigation instrument is also used for creating tracks with the use of radar contacts.
- Speed and Distance Log Device. Speed and distance log device is a piece of navigation equipment used for measuring the speed and distance that the ship travels from a particular reference point.
- Pilot Card. A pilot card is a booklet of information provided to the pilot of the ship. It consists of information about the ship such as dimension, draught maneuvering, propulsion equipment, turning circle, etc.
