The fiber optic gyroscope compass consists of three fiber optic gyroscopes installed perpendicular to each other and three accelerators

The thermometer, along with its corresponding circuit board and computer components, has no moving parts. Fiber optic gyrocompass belongs to the strapdown inertial navigation system. Through the operation of specialized software in the internal computer, the navigation parameters of the carrier, such as heading, pitch and roll, and angular rate, can be calculated.
