AHRS-II-P Professional

Description

AHRS-II-P Professional by Inertial labs, is the next generation of enhanced, high-performance strapdown systems that determines absolute orientation (Heading, Pitch and Roll) for any device on which it is mounted.

The AHRS-II-P utilizes 3-axes each of precision accelerometers, magnetometers and gyroscopes to provide accurate Heave, 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 axes. Accelerometers and Fluxgate magnetometer measure absolute Pitch, Roll and magnetic Azimuth at AHRS initial alignment as well as providing ongoing corrections to gyroscopes during operation.

One of the key elements to the success of Intertial Labs AHRS-II is its use of Inertial Labs 8mm 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 addtion 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.
