The AHR50 Embeddable AHRS is the lightest and most compact AHRS on the market with "Mission Critical" DAL A software certification. No matter what your size, weight, and cost contraints, it is never safe to cut corners on the flight controls. The AHR50 is here to ensure that you have an AHRS that fits your design needs while providing your customers with the peace of mind that their flight will be a safe one.

The AHR50 Embeddable AHRS is Archangel’s recommendation for the smaller and more compact UAM platforms. This instrument weighs in at as little as 77 grams (0.17lbs) and fits in a 1.25″ x 2.5″ x 2.0″ (H x W x D) space. The AHR50 maintains the full DO-178 DAL A certification of the other AHRS/ADAHRS lines and has partial DO-160 environmental certification. This unit is often embedded into larger DO-160 boxes such as a flight controller in order to maintain the full environmental protection. With both integrated sensor suites and additional input capabilities, the AHR50 can function as an AHRS (Attitude Heading Reference System) or and embedded INS (Inertial Navigation System).

Archangel’s AHR150A-2 MSU provides heading data for the AHR50, and it is fully qualified to DO-160E, DO-178B Level A, and TSO C6e. Unlike most AHRS, the AHR50 can also accept air data information via RS-232 and blend it with inertial measurements to enhance attitude estimates.
