10 Axis MEMS IMU Inertial Measurement Unit For Attitude Control In UAVs Loitering Munitions SI-MIMU-P
SI-MIMU-P is a 10-degree-of-freedom inertial measurement unit (IMU) based on micro-electro-mechanical systems (MEMS) technology, featuring small size, high performance and low cost. It is mainly used to sense the angular rate, acceleration, magnetic field strength of the system carrier along three orthogonal axes, as well as the air pressure in the area where the carrier is located, and output the collected information through digital signals.
The SI-MIMU-P inertial measurement unit has built-in algorithms and compensation software for full-temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc. These ensure the product's stable and excellent performance under both static and dynamic conditions, and guarantee that it can still provide users with excellent and reliable measurement data under harsh environmental conditions.
