Inertial Labs miniAHRS Miniature AHRS
The MminiAHRS from Inertial Labs, a miniature Attitude and Heading Reference System (AHRS), is a high-performance strapdown system 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.
Description
Overview
The miniAHRS miniature AHRS from Inertial Labs utilizes 3-axis each of precision accelerometers, magnetometers and gyroscopes to provide accurate Heading, Pitch and Roll of the device under measure. Integration of gyroscopes’ output provides high frequency, real-time measurement of the device rotation about all three rotational axis. The accelerometers and fluxgate magnetometer measure absolute Pitch, Roll and magnetic Azimuth at AHRS initial alignment and provide ongoing corrections to gyroscopes during operation.
One of the key elements to the success of Inertial Labs AHRS is its use of mini fluxgate magnetometers which have distinct advantages over commonly used magneto-inductive or magneto-resistive 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.
