The Rockwell Collins AHS-1000() Attitude Heading Reference System (AHRS) is more accurate, far more reliable and has a lower life-cycle cost than conventional systems. Designed to replace previous-generation analog and iron gyro systems, it features no moving parts and up to 10,000 hours mean time between failure, helping to ensure reliability and dispatchability. What's more, the system is built to withstand extreme environments involving high roll rates and vibration and is designed for operation in helicopter, fixed-wing aircraft and military training aircraft.
