The Collins Aerospace AHS-4000 Attitude and Heading Reference System (AHRS) features a distinctive solid-state design in a small, lightweight package. The embedded low-power fiber-optic gyro and triple-axis MEMS accelerometers ensure high reliability and low power consumption. Continuous monitoring of all functions and internal diagnostics gives you a high-integrity system.
You can operate the AHS-4000 in several modes to provide your aircraft with the most accurate navigation data based on available inputs. After self-aligning, the system operates like an Inertial Reference System, providing free inertial navigation position and velocity outputs along with the basic AHRS functions. For higher precision calculations, the AHS-4000 can use GPS inputs.
