STIM210 低成本高精度陀螺仪

STIM210是一款小巧、价格适中、在恶劣环境下仍能可靠工作的高性能硅基MEMS陀螺模组，多可容纳3轴。它不受国际武器贸易协定(ITAR)约束，非常适用于工业、航天及国防领域的平台稳定系统、导航与控制等应用。它重量轻(52g)、启动时间短、全温范围零偏低等优异性能为MEMS陀螺模组树立了行业标杆。模组出厂前经过校准并在全工作温度范围内进行温度补偿，它的零偏不稳定性为0.5°/h，ARW小于0.15°/√h，支持外触发输入、数据时间戳和高达2kHz的采样率。全工作温度范围内的零偏稳定性为10°/h。系统设计者会毫不犹豫地选择STIM210来替代大且昂贵、脆弱且易磨损的现用光纤陀螺仪(FOG)、石英或其它机械陀螺传感器。
Miniature package

Excellent environmental robustness
1, 2 or 3 axes offered in same package
Electronically calibrated axis alignment
Plug & play high-level RS422 interface
24 bits resolution
Single-crystal silicon technology

Fully configurable:
- 5 different sampling rates available
- 5 different bandwidths available
- LP filter -3dB frequency can be set individually for each axis
- RS422 protocol, bit rate and line termination
- Selectable output unit: angular rate [deg/s] or incremental angle [deg]
Continuous self-diagnosticsPerformanceEach 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 "plug & play" high-level 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 intermediately 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.
