STIM202 3-Axis MEMS gyro

Miniature, tactical-grade gyroscope with high shock resistance

STIM202 3-Axis MEMS gyroThe STIM202 is a 3-axis tactical-grade 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.

STIM210 Ultra High-Performance MEMS Gyro

Miniature tactical-grade gyroscope with 1-3 axes

STIM210 Ultra High-Performance MEMS GyroThe STIM210 is a tactical-grade MEMS gyro module that can be provided with one, two or three axes of measurement.

The unit features high resistance to shock and improved bias error over temperature gradients and improved non-linearity.

The module features an integrated 32-bit RISC ARM microcontroller, providing selectable output formats including angular rate, increment angle, average angular rate and integrated angle, as well as a configurable sample rate of up to 2000 samples per second.

All axes of the STIM210 are factory-calibrated for bias and sensitivity, and compensated for temperature effects across the entire operating range.

STIM277H 3-Axis Hermetic MEMS Gyro

Hermetically-sealed tactical-grade MEMS gyroscope for space & defense

STIM277H 3-Axis Hermetic MEMS Gyro The STIM277H is a tactical-grade 3-axis MEMS gyro module that has been hermetically sealed and designed to meet the exceptional long-term reliability and stability needs of space and defense applications. Housed in an aluminium enclosure with SurTec650 surface treatment and a glass-to-metal sealed electrical Micro-D connector, the unit has been HTOL (high-temperature operating life) tested for a 20+ year lifespan.

Based on and backwards-compatible with the STIM210, the high-performance module incorporates a 32-bit RISC ARM microcontroller, providing a wide variety of configurable options such as output formats, sampling rate, LP filter cut-off frequency and RS422 transmission bit rate.

The STIM277H has been factory-calibrated across all axes for bias and sensitivity, and compensated for temperature effects. All components have been tested for fine and gross leak according to MIL-STD-883J.
