High Performance MEMS IMU
Introduction
The GSY-MIMU-M02 is an inertial measurement unit (IMU) based on micro-mechanical technology (MEMS), including a built-in MEMS gyroscope with 2¡ã/h (Allan) bias stability and a MEMS accelerometer with 100 µg (Allan) bias stability, which outputs three-axis angular velocity and three-axis acceleration, three-axis magnetometer and barometer.
The product has high reliability and strong environmental adaptability. That is, it can be widely used in fields such as drones, smart bombs, seekers, rocket shells and stable platforms.
Features
