UM7 Orientation Sensor

UM7 Orientation Sensor: a leading-edge IMU

The UM7 orientation sensor is a 3rd-generation IMU that takes advantage of state-of-the-art MEMS technology. It combines triaxial accelerometer, rate gyro, and magnetometer data using a sophisticated extended Kalman filter to produce orientation, heading, and speed estimates accurately and consistently. What’s more, this compact and lightweight module with an angular resolution of 0.01° is offered at an affordable price!

Added features from Redshift Labs

In addition to these very well-known characteristics, the UM7 IMU integrates many new features, including:

• Higher gyro bias stability;
• Lower noise;
• A new communication architecture for improved flexibility;
• NMEA packet transmission;
• UTC time synchronisation with external GPS, and much more!
