gyro-compass

A ship's captain checks the gyro-compass on the bridge.

Definition

1. Noun:
   • A navigational instrument: A "gyro-compass" is a compass that uses a continuously driven gyroscope to automatically and continuously seek geographic (true) north, rather than magnetic north. It is not affected by magnetic fields, making it reliable for ships and aircraft.

Usage Examples

• (The navigational tool using a gyroscope showed true north correctly.)
• (The instrument helps maintain direction without magnetic interference.)

Advanced Usage

• "Gyro-compass alignment": the process of calibrating the gyro-compass to ensure it points to true north.

  • The crew performed gyro-compass alignment before departure. (They adjusted the instrument to show correct true north.)

• "Gyro-compass error": a deviation in the gyro-compass reading due to factors like speed or latitude.

  • The navigator compensated for gyro-compass error caused by the ship's rapid movement. (They corrected the instrument's inaccuracy.)

Variants and Related Words

• Gyro-compass (n): the primary spelling, often hyphenated.
• Gyrocompass (n): an alternative spelling without the hyphen, equally common.
  • The gyrocompass system was installed in the new submarine. (The same instrument, written as one word.)

Synonyms
