MEMS IMU
The nine-axis MEMS inertial measurement unit is composed of three-axis MEMS gyro chips, three-axis MEMS accelerometer chips, three-axis magnetometer chips, atmospheric pressure sensors, temperature sensors, digital signal processing circuits, structure, and software. It is used to measure the real-time three-axis angular velocity and linear acceleration of the carrier. It is compatible with ADIS16488 series products.
The product utilizes a unique structural design, with software incorporating algorithms such as full-temperature compensation, installation misalignment angle compensation, and nonlinear compensation. This ensures excellent performance even in static, dynamic, and harsh environmental conditions, providing users with excellent and reliable measurement data.
