Overview

The AHRS-10B from Inertial Labs is a new generation MEMS AHRS that determines absolute orientation (heading, pitch & roll) for any device on which it is mounted. Orientation is determined with high accuracy for both motionless and dynamic applications.

The AHRS-10B utilizes 3-axis each of precision accelerometers, magnetometers and gyroscopes to provide accurate heading, pitch and roll of the device under measure. Integration of the gyroscopes’ output provides high frequency, realtime measurement of the device rotation about all three rotational axis.

The accelerometers and fluxgate magnetometer of the AHRS-10B measure absolute pitch, roll and magnetic Azimuth during the AHRS initial alignment as well as providing ongoing corrections to gyroscopes during operation. The AHRS-10B offers state-of-the-art algorithms for different dynamic motions of robots, UAV, UUV, UGV, AGV, ROV, gimbals and antennas.

One of the key elements to the success of every Inertial Labs AHRS is its use 8 mm fluxgate magnetometers which have distinct advantages over commonly used magneto inductive or magnetoresistive magnetometers. In operation over time and temperature, fluxgate magnetometers have superior stability and repeatability. In terms of sensitivity, fluxgate magnetometers provide up to two orders of magnitude increased sensitivity.

In addition to the performance advantages, unlike the chip-level magnetometer technology, fluxgate magnetometer technology has been depended on for over 70 years to provide an accurate reference to North. It remains the most reliable magnetic sensor technology for determining an object’s heading.
