Fibre optic gyrocompass
The fibre optic gyrocompass is a complete unit, which unlike a conventional compass, has no rotating or other moving parts. It uses a series of fibre optic gyroscope sensors and computers to locate north. It has very high reliability and requires little maintenance during its service life. The entire system usually includes a sensor unit, a control and display unit, and an interface and power supply unit. It is often linked with the ship's other navigational devices including GPS.
