The Fiber Optic Gyro (FOG) is a highly advanced type of gyro used in marine navigation systems. Unlike traditional mechanical gyros, FOGs use light signals to measure changes in orientation. This technology allows for extreme accuracy and stability, making it an ideal choice for precision navigation on commercial vessels, yachts, and submarines. FOG systems offer faster response times and lower power consumption compared to other types of gyros. As a result, they provide reliable heading data, even under the most challenging conditions, and are increasingly popular in modern marine applications.
