TJ-MIMU-K
PRODUCT INTRODUCTION
TJ-MIMU-K micro-inertial measurement unit is a small, high-performance, low-cost micro-inertial measurement unit based on micro-electro-mechanical system (MEMS) technology. It is mainly used to measure angular velocity and acceleration information on three orthogonal axes of sensitive system carriers, and outputs digital signals proportional to the angular velocity and acceleration of the carrier.
TJ-MIMU-K micro-inertial measurement combination has built-in full temperature compensation, installation misalignment angle compensation, nonlinear compensation, and other algorithms and compensation software, which ensure the stable and excellent performance of the product under static and dynamic conditions, and ensure that it can still provide users with excellent and reliable measurement data under harsh environmental conditions.
