MEMS Inertial Measurement Unit

Safran manufactures a range of Inertial Measurement Units with STIM300 being the first one released in 2011.

Since then it has been through a range of improvements and added features. Backward compatibility is always maintained to support our long-term customers.

Next, the STIM318 with improved accelerometers came and then soon to follow, the STIM320 with further improvements to the gyro performance.

STIM377H, a hermetically sealed IMU introduced in 2020, aimed at applications that require the highest long term reliability, tested to 20+ years life expectancy.

All IMUs share the identical form factor and Safran's proprietary and reliable inertia technology manufactured in its own wafer fab since 2002. The STIM series of IMUs are today the highest performing ITAR-free IMUs commercially available in the market in its size class.
