Gyrocompass · Position & Heading
Raytheon Anschütz Standard 22 is the most widely used gyrocompass on merchant vessels worldwide. Produced in various variants since 1990. The newer Horizon series uses fiber-optic gyroscope (FOG) technology without a rotating mass — requiring less maintenance and being more resistant to vibration. Anschütz developed the first marine gyrocompass in 1908 and has dominated the market ever since.
