STIM210 MEMS GYROSCOPE
3 AXES MODULE
View all MEMS Gyroscope options.
STIM210 is a small, tactical grade, affordable, robust and reliable, ultra high performance (Bias Stability 0.3°/h, ARW 0.15°/√h) MEMS gyro module with up to 3 axes. An integrated 32-bit microcontroller enables flexible user configuration. Electronic axis alignment is standard.
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 more advanced users, STIM210 may be put in Service Mode. In this mode all the configuration parameters can be temporarily or permanently changed by overwriting the current settings in the flash memory. Service Mode also provides the ability to perform single measurements, perform diagnostics and obtain a higher detail in the status byte.
ADVANTAGES
Shock & Vibration Resistant
The STIM 3-Axes MEMS Gyroscope Modules perform exceptionally well across many applications due to their very low vibration and shock sensitivity. They are designed to withstand 1500g of shock forces. Due to this extreme shock resistant capability, the gyroscopes are qualified according to high-performance aircraft vibration standards.
Reliability and Robustness
STIM210 (three axes) modules have an MTBF at 70k operating hours (according to MIL-HDBK 217), which is outperforming current FOG systems. Tuning of excitation and detection frequencies, as well as perfectly balanced vibrational masses, result in very low vibration and shock sensitivity in any direction.
Multi-Application Support
STIM210 applications are typically found within Industrial, Aerospace and Defense markets, for various platform stabilizations, pointing and navigation systems (e.g. antennas, cameras and gimbals), attitude heading reference systems (AHRSs), inertial navigation systems (INSs) for UAVs, AUVs, AGVs, UGVs and ROVs, smart munitions, 3D mapping systems, range finders, trains, robotics and more. For many applications STIM210 directly replaces FOGs and improves system solutions with respect to robustness, reliability, size, weight, power and cost. STIM210 can also open new markets, where adequate solutions previously have not yet been possible to realize.
