High-performance Navigation MEMS IMU

High-performance Navigation MEMS IMU

Introduction
The Inertial Measurement Unit (IMU) is a device that measures the three-axis attitude angles (or angular velocities) and accelerations of an object. Gyroscopes and accelerometers are the core components of an Inertial Navigation System (INS). By using the built-in accelerometers and gyroscopes, the IMU can measure the three-axis linear accelerations and three-axis rotational angular velocities, and obtain the information of the carrier's attitude, velocity and displacement through analysis. The ER-MIMU-182 uses high-quality and highly reliable MEMS accelerometers and gyroscopes.
