Introducing Archangel's flagship aviation products-the AHR150A and AHR300A ADAHRS. With FOG-equivalent attitude accuracy, these products provide affordable, reliable inertial data for both fixed- and rotary-wing platforms.
The AHR150A and AHR300A represent a paradigm shift in the ADAHRS market. Using MEMS sensors and sophisticated blending algorithms, the AHR150A and AHR300A yield "FOG-grade" performance at greatly reduced size, weight, power, and cost. Several companies, including The Boeing Company and Erickson Air-Crane, have selected the AHR150A for their supplemental type certificates in both rotary- and fixed-wing platforms.
The AHR150A and AHR300A systems consist of two boxes. The AHR150A-1 (or AHR300A-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.
Both the AHR150A and the AHR300A offer similar features, but the rate limit of the AHR150A reaches ±128°/second while the AHR300 reaches ±256°/second. Both products include multiple high- and low-speed ARINC ports, allowing them to integrate seamlessly into any modern avionics suite.
