This paper describes a 0.1 deg/hr fiber optic gyroscope (FOG) controlled exclusively by a high-speed digital signal processor (DSP). The sampling time of all control loops equals the transition time of the light through the sensor coil. The device uses a 500 m fiber sensor coil and operates in closed-loop mode. The control and compensation algorithms where implemented in software and are carried out by a single high-speed DSP. The processor also takes care of the communication protocol via a high-speed synchronous serial bus. This single-axis FOG was designed in a modular structure and is the basic building block for the LFK95 system; a low-cost maritime gyrocompass for commercial applications. The system also fulfills serial bus, maritime gyroscompass, modular structure.
