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，最多可容纳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。
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 (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.
