STIM210是一款小巧、價(jià)格適中、在惡劣環(huán)境下仍能可靠工作的高性能硅基MEMS陀螺模組，最多可容納3軸。它不受國際武器貿(mào)易協(xié)定(ITAR)約束，非常適用于工業(yè)、航天及國防領(lǐng)域的平臺(tái)穩(wěn)定系統(tǒng)、導(dǎo)航與控制等應(yīng)用。它重量輕(52g)、啟動(dòng)時(shí)間短、全溫范圍零偏低等優(yōu)異性能為MEMS陀螺模組樹立了行業(yè)標(biāo)桿。模組出廠前經(jīng)過校準(zhǔn)并在全工作溫度范圍內(nèi)進(jìn)行溫度補(bǔ)償，它的零偏不穩(wěn)定性為0.5°/h，ARW小于0.15°/√h，支持外觸發(fā)輸入、數(shù)據(jù)時(shí)間戳和高達(dá) 2kHz的采樣率。全工作溫度范圍內(nèi)的零偏穩(wěn)定性為10°/h。系統(tǒng)設(shè)計(jì)者會(huì)毫不猶豫地選擇STIM210來替代大且昂貴、脆弱且易磨損的現(xiàn)用光纖陀螺儀(FOG)、石英或其它機(jī)械陀螺傳感器。
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.
