MFOG-24 Aerospace Fiber Optic Gyroscope 1.5 deg/h Bias for Satellite Attitude Control Systems
The MFOG-24 is an aerospace-grade fiber optic gyroscope configured for satellite attitude determination and control systems (ADCS). Its solid-state construction with radiation-tolerant optical components provides reliable angular rate sensing in the harsh space environment.
Leveraging the Sagnac effect with polarization-maintaining fiber coil, the MFOG-24 achieves 1.5 deg/h bias stability with 0.03 deg/rt-h angular random walk. The vacuum-compatible design and wide operating temperature range make it suitable for LEO satellite missions.
- Radiation-tolerant optical components for LEO space environment
- Angular rate range: +/-500 deg/s, zero-bias stability
- Angular random walk:
- Operating temperature: -40 to +65 deg C for satellite thermal conditions
- No moving parts eliminates lubrication and mechanical failure modes
- Compact phi24x39mm, 30g minimizes payload mass budget
