STIM202 MEMS GYROSCOPE

3 AXES MEMS GYROSCOPE MODULE

STIM202 is a 3-axis shock capable, tactical grade, affordable, robust and reliable, ultra high performance (Bias Stability 0.4 °/h, ARW 0.17 °/√h) MEMS Gyro module. An integrated 32-bit Microcontroller enables flexible user configuration.

STIM202 is designed with internal shock absorbers for operation in environments with high shocks. It is capable for direct mounting on a range of firing defense applications like remote weapon stations(RWS).

Each axis is factory calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements. The unit runs off a single +5V supply and communicates via a RS422 interface. The use of a 32-bit RISC ARM microcontroller provides flexibility in the configuration, like choice of output unit, sampling frequency, LP filter -3dB frequency and RS422 bit-rate and protocol parameters. For advanced users, STIM202 may be put in Service Mode. In this mode all the configuration parameters can be temporarily or permanently adjusted according to the customer’s requirements. Service Mode also provides the ability to perform single measurements, perform diagnostics and obtain a higher detail in the status byte.

ADVANTAGES

Reliability & Resiliency

Perfect tuning of excitation and detection frequencies, as well as
perfectly balanced vibrational masses, result in very low sensitivity
to vibration and shock. For use in extreme environments, the
STIM202 provides a vibration isolated internal assembly to avoid
rectification errors.
Extensive Input Range, Orthogonality and Ouput Formats

The STIM202 full-scale angular rate input range is 400 °/s and the
output is capped at ±480 °/s. 3-axis modules feature electronic axis
alignment, improving orthogonality between axis (down to 1 mrad).
Selectable output formats are angular rate, increment angle,
average angular rate and integrated angle, at sampling rates up to
1000 samples per second.
Mission-Critical Applications

Typical STIM202 applications are attitude heading reference
systems (AHRSs), platform stabilization and pointing systems
(antennas, cameras, gimbals,..), high performance industrial
applications, unmanned aerial vehicles (UAVs), autonomous
underwater vehicles (AUVs), automated ground vehicles (AGVs),
space applications, and more. STIM202 can also open new
markets, where adequate solutions previously have not yet been
possible to realize.
