gyrocompass: meaning, definition, pronunciation and examples

No. A GPS uses satellite signals to determine position. A gyrocompass is a self-contained mechanical/electrical instrument that finds true north using Earth's rotation. They are often used together in integrated navigation systems.

A gyrocompass provides continuous, instant directional heading (which way the bow is pointing). GPS provides position (latitude/longitude) but heading must be derived from movement, which is slow or inaccurate when moving slowly or stationary. A gyrocompass is also a critical backup if GPS fails.

Modern gyrocompasses are designed to work at all latitudes, including the equator. However, very high-precision models may have reduced accuracy or require special settings at extreme latitudes near the poles.

It is the small, predictable difference between the direction indicated by the gyrocompass and true geographic north. It is caused by the ship's motion, speed, and latitude. Navigators apply this correction to get the most accurate heading.

A non-magnetic compass that uses a fast-spinning gyroscope and the rotation of the Earth to find true north.

Gyrocompass is usually technical in register.
