High Accuracy MEMS Inertial Sensors: Tactical-Grade MEMS IMU & MEMS Gyroscopes

STIM202 3-Axis MEMS gyro

Miniature, tactical-grade gyroscope with high shock resistance

The STIM202 is a 3-axis MEMS gyro module with internal shock absorbers that work as a low pass filter, allowing the unit to operate unaffected in environments with shocks containing high energy across a large frequency spectra.

The module can replace FOGs (fiber optic gyros) in many applications, providing a lower SWaP (size, weight and power) footprint and a highly reliable and robust solution.

The module features an integrated 32-bit RISC ARM microcontroller, allowing users to configure a wide range of parameters such as output formats, sampling rate, LP filter cut-off frequency, RS422 transmission bit rate and more.

Each of the module’s three axes has been electronically aligned and factory-calibrated for bias and sensitivity, and temperature compensated over the full operating range.
