An azimuth circle is a navigational instrument used with a ship’s compass to measure bearings of celestial bodies or landmarks. It consists of a graduated ring mounted on the compass, allowing mariners to determine the ship’s heading relative to a fixed point. Essential for traditional navigation, the azimuth circle aids in accurate course plotting and […]

Calibration of a marine gyrocompass is crucial to ensure accurate heading data. Over time, the gyrocompass may drift or accumulate errors, affecting its performance. Proper calibration aligns the compass to true north, ensuring that the vessel’s navigation system can provide precise heading information. This process involves adjustments to correct the errors caused by environmental factors […]
The gyrocompass provides numerous advantages over a magnetic compass. It operates independently of magnetic fields, making it highly accurate and reliable in all geographical locations, including polar regions where magnetic compasses fail. Gyrocompasses also support advanced integration with radar, ECDIS, and autopilot systems, enabling precise course control. While magnetic compasses are affected by deviation and […]
