Inertial Labs, Inc. AHRS Attitude & Heading Reference Systems

Integration of Tactical-grade IMU with Gyro-compensated Fluxgate Compass

The Inertial Labs Attitude and Heading Reference Systems are enhanced, high-performance strapdown systems, that determines absolute orientation (Heading, Pitch and Roll) for any device on which it is mounted. Orientation is determined with high accuracy for both motionless and dynamic applications.
The Inertial Labs AHRS utilizes 3-axes each of precision accelerometers, magnetometers and gyroscopes to provide accurate Heave, Heading and Attitude of the device under measure.
