Brief Introduction
FOG70M is a high performance single-axis digital fiber optic gyroscope, which offers significant performance in such critical areas such as bias stability, bias repeatability, scale factor, scale factor linearity, and maximum input rate. FOG70M fiber optic gyro adopts advanced integrated optics and closed-loop Digital Signal Processing (DSP), and enjoys exceptional low noise, insensitivity to cross-axis error, perfect shock
and vibration robustness, short startup time, small size, light weight, wide bandwidth, low power consumption, competitive price and excellent magnetic shielding advantages.
SkyMEMS's FOGs are setting the new benchmark for tactical and navigational grade gyros for a wide variety of guidance, navigation and aeronautics applications. And FOG70M has been widely used in motion sensing, stabilization, navigation, vehicle north seeker, airborne attitude, boat gyrocompass and precision pointing applications, etc.
