The SI‑MIMU‑K Micro Inertial Measurement Unit (IMU) is a compact, high‑performance and cost‑effective MEMS inertial sensor designed to measure three‑dimensional angular velocity and linear acceleration of moving carriers.
Embedded with comprehensive compensation algorithms covering full‑temperature range, axis‑to‑axis misalignment and nonlinearity, the SI‑MIMU‑K delivers consistent, superior performance under static conditions as well as vehicle‑borne dynamic scenarios. It outputs highly reliable inertial measurement data even in demanding harsh environments.
Suited for UAVs, loitering munitions, unmanned surface vehicles, AGVs and intelligent mobility systems, this unit serves as a core inertial sensing component for attitude determination, motion sensing and navigation applications.
