FMU series

Capitalizing on Safran Electronics & Defense's 60-year experience in inertial systems, these units are equipped with FOG gyro technology and servo-looped MEMS accelerometers.
FMU IMUs, as well as their packaged versions, are particularly designed for civil and industrial applications which need to combine very high reliability, excellent signal stability and very low noise.

FMU: FOG Inertial Measurement Units

Thanks to its 3 HRG sensors, Safran Electronics & Defense's PRIMUS Inertial Measurement Unit family achieves high performance in a small size and is perfectly ready for integration into applications even with the most demanding requirements.

PRIMUS: Hemispherical Resonator Gyro Inertial Measurement Unit
Rate Gyro Unit 10 20 & 30MS56 series

These units are equipped with a rugged single axis solid state vibrating rate gyro, which takes benefits of the 60 years of Safran Electronics & Defense experience in inertial systems.
The MS56 series is particularly designed for civil and industrial applications which need to combine very low signal noise and low cost.
Safran, due to its expertise covering all gyro's technologies (vibrating gyros, wheeled mechanical gyros, optical fibre and laser gyros) is able to propose the right technology for the best compromise between cost and accuracy required for each stabilisation requirement.

Rate Gyro Unit 20BM60 series

Among the wide pannel of inertial sensors designed and manufactured by Safran Electronics & Defense, a dynamically tuned gyroscope has been selected in order to offer to the user the best compromise between accuracy required for stabilization purposes, robustness, reliability, and price. These units also include a DC/DC converter and filters fully compliant with Mil Std 461 and Mil Std 1275.
