Low Bias Fiber Optic Gyroscope 1.5 deg/h Bias for INS GPS Integrated Navigation Systems
The MFOG-24 is a precision fiber optic gyroscope optimized as the angular rate sensing element in INS/GPS integrated navigation systems. Its low 0.03 deg/rt-h angular random walk and stable bias characteristics provide reliable dead-reckoning during GPS signal outages.
Utilizing the Sagnac effect with temperature-compensated output, the MFOG-24 maintains consistent performance across the full -40 to +65 deg C operating range. Compact phi24x39mm packaging enables easy integration into existing INS enclosures.
- Low 0.03 deg/rt-h ARW for accurate dead-reckoning during GPS outages
- Angular rate range: +/-500 deg/s, zero-bias stability <=1.5 deg/h (1 sigma)
- Temperature-compensated output for stable performance -40 to +65 deg C
- Rapid start-up with no warm-up drift for mission-critical INS applications
- Analog output compatible with common INS sensor fusion processors
- Compact phi24x39mm, 30g fits standard INS IMU enclosures
