The UM7 Orientation Sensor is a third generation orientation system (AHRS) from Redshift Labs that generates attitude and heading information from triaxial acceleration sensors, speed gyros and magnetometer data. Unlike a typical turbidity measurement unit (IMU) that only provides raw sensor values, the UM7 features an integrated microcontroller that combines sensor data with a sophisticated Extended Kalman Filter (EKF) to generate 500 times per second of orientation changes.

The UM7 has a number of improvements over its predecessor, the UM6, including higher gyro bias stability and lower noise, a new communications architecture for the UM6;for more flexibility, optional NMEA packet transmission, UTC time synchronization with external GPS and support for third-order temperature compensation on all sensors. It takes advantage of the newer micro-electro-mechanical systems (MEMS) technology, which makes it possible to offer better performance at a lower price.
