Input range, orthogonality and output formats
The STIM210 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 1mrad). Selectable output formats are angular rate, increment angle, average angular rate and integrated angle, at sample rates up to 2000 samples per second.
Reliability and robustness
STIM210 modules have MTBF > 120k hours per axis (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.
Power and interface
The unit is powered by a single +5V supply and communicates via a Plug- and-Play high-level RS422 interface at bit rates up to 1.8 Mbits/s.
Device configurations and self diagnostics
The use of a 32-bit RISC ARM microcontroller provides flexibility in device configuration. Choices for output unit, sample rate, LP filter cut-off frequency, RS422 transmission bit rate, line termination ON/OFF, etc. can be done in device Service Mode. The Service Mode also provides the ability to perform single measurements on demand and access detailed diagnostics information.
evaluation kits
STIM210 evaluation kits for PCI and USB connectivity are available. The PCI kit is the recommended choice for thorough characterization. The PCI kit supports all STIM210 RS422 transmission bit rates (374400, 460800, 921600 and 1843200 bits/s). The USB kit is the alternative solution, e.g. for smaller, portable laptop setups, providing an excellent choice for quick gyro module configurations and shorter measurement series. The USB kit supports the default STIM210 RS422 transmission bit rate (460800 bits/s).
Application areas
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.
