gyrocompass
The gyrocompass aboard the National Oceanic and Atmospheric Administration's (NOAA) ship Rainier. Gyrocompasses are navigational instruments that use a continuously driven gyroscope to accurately seek the direction of true (geographic) north.
The master gyrocompass is typically installed in a protected, climate-controlled compartment to shield it from the external environment and ensure its sensitive components remain stable.1
Because the master unit is often located away from the primary control area, repeaters are mounted on the shipâs bridge and other necessary locations to provide the crew with immediate, accurate access to the vessel's heading information. These repeaters allow for continuous navigation and monitoring of the ship's course directly from the bridge without requiring access to the master unit's protected housing.1
