AHR150A/AHR300A
- Archangel’s flagship aviation products are the AHR150A and AHR300A ADAHRS.
- Both the AHR150A and the AHR300A offer similar features and certifications. The primary difference is the rate limits of ±128°/second for the ‘150A and ±256°/second for the ‘300A Both products include multiple high- and low-speed ARINC ports, allowing them to integrate seamlessly into any modern avionics suite.
With FOG-equivalent attitude accuracy, these products provide affordable, reliable inertial data for both fixed- and rotary-wing platforms. Both of these products have been proven as excellent replacements of legacy DGVG sets or antiquated AHRS/ADAHRS to modernize your aircraft.
The AHR150A system consist of two boxes. The AHR150A-1 Inertial Sensing Unit (ISU) is the rate, acceleration, and air data sensing component while the AHR150A-2 Magnetic Sensing Unit (MSU) is a remote 3 axis magnetic field sensing device. Together, these two units provide a powerful and cost-effective alternative to Fiber Optic Gyro systems.
The AHR150A and AHR300A systems are Archangel’s recommendations for larger and more sophisticated eVTOL platforms.

The AHR150A ADAHRS is an excellent choice for high caliber eVTOL platforms that require a source of airdata. Budgets for size, weight, power and cost are low, DO-160 certification levels are rigorous, software is DO-178 DAL A certified, and TSO approvals are secured. Equally important, the accuracy and latency of acceleration and rate data support autonomous flight controls.

There is substantial pressure from the FAA and EASA to avoid catastrophe with this new class of emerging aircraft. Likewise, there is a pressure on eVTOL developers to reduce the costs of their system in order to compete in an increasingly crowded market with significant barriers to entry. The AHR150A maintains an affordable price point while also checking off every potential box that the FAA or EASA may look to when deciding whether or not a eVTOL system should be certified. If the FAA and EASA will not support your design, then the aircraft will not be brought to market. Let Archangel take this pressing concern off your hands and free you up to focus on the bigger picture.
