AH-1000 Attitude and Heading Reference Systems (AHRS)
Overview
Our AH-1000 is a micro-electromechanical system (MEMS) attitude and heading reference system (AHRS) designed to serve as the attitude and heading reference system of choice for commercial aerospace primary or secondary attitude and heading systems.
The AH-1000 attitude and heading reference system was designed to provide unparalleled reliability and performance with significantly reduced size and weight compared to similar systems. This design allows the AH-1000 to provide the lowest total cost of ownership experience for an ARINC-705 AHRS.
