DESCRIPTION
STIM210 is a multi-axis gyro module with up to 3 axes of highly accurate MEMS gyros. Each axis is factory calibrated for bias and sensitivity, and compensated for temperature effects. This new design of the STIM200-series allows for an improved bias error over temperature gradients （10°/h） and an improved non-linearity （nom. 50ppm BSL over FS）.
STIM210 industrialization is realized by combining the well proven Sensor ButterflyGyroTM technology with a full digital operation.
Input range, orthogonality and output formats The STIM210 full-scale angular rate input range is 400°/s.
3-axis modules feature electronic axis alignment, further improving orthogonality between axis （down to 1mrad）.
Selectable output formats are angular rate, increment angle, average angular rate and integrated angle, at sampling rates up to 2000 samples per second.
Reliability and robustness STIM210 modules have MTBF > 120k hours per axis （according to MIL-HDBK 217）, outperforming current FOG systems.
Perfect tuning of excitation and detection frequencies, as well as perfectly balanced vibrational masses, result in very low vibration and shock sensitivity in any direction.
Power and Interface The unit is powered by a single +5V supply and communicates via a Plug-and-Play high-level RS422 interface at a bit rate of up to 1.84Mbits/s.
Device configurations and self diagnostics The use of a 32-bit RISC ARM microcontroller provides flexibility in configuration. Choices for output unit, sampling frequency, LP filter cut-off frequency, RS422 transmission bit rate, line termination ON/OFF, etc. can be done in the Service Mode. The Service Mode also provides the ability to perform single measurements on demand and access detailed diagnostics information.
Evaluation kits and kit add-on STIM210 evaluation kits for PCI and USB are available. The PCI solution is recommended for thorough characterization and device configuration, supporting all RS422 transmission bit rates （374400, 460800, 921600 and 1843200 bits/s）.
The USB solution is recommended for easy evaluation and device configuration, supporting default RS422 transmission bit rate （460800 bits/s）.
Application areas STIM210 applications are typically found within Industrial, Aerospace and Defence markets, for platform stabilizations （for antennas, cameras and various gimbals）, attitude heading reference systems （AHRSs）, inertial navigation systems （INSs for UAVs, AUVs, AGVs, UGVs and ROVs）, smart munitions, missiles, 3D mapping systems, range finders, trains, robotics, and more.
For many applications STIM210 can directly replace FOGs and improves system solutions with respect to robustness, reliability, size, weight, power and cost. STIM210 can also open new markets, where previously it would not have been possible to realize adequate solutions.
