AHR75 Attitude Heading Reference System

AHR75 Attitude Heading Reference System

The AHR75 AHRS is designed specifically to provide high levels of performance at a low cost. In creating the AHR75, Archangel Systems uses a three-part design philosophy: technology, certifications, and ease of use.

First, the AHR75 uses technology including MEMS sensors, Archangel's AHR150A-2 magnetic sensing unit, and sophisticated blending algorithms to deliver "FOG-grade" performance at greatly reduced size, weight, and power. Second, the unit has a comprehensive list of certifications including FAA approval for Part 23, 25, 27, and 29 installations, DO-178C Level A (Mission Critical) software, and complete DO160E protections. Third, the AHR75 is easy to install and use. With multiple high- and low-speed ARINC 429 ports, the AHR75 directly integrates into modern architecture and functions seamlessly with Archangel's AHR150A-2 MSU.
