STIM210 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 consists of 1, 2 or 3 ultra high accuracy gyros in a miniature package with a RS422 interface. The module function is based on an integrated 32-bit microcontroller that provides flexibility in the configuration. Electronic axis alignment is standard.
