Horizon AD/AHRS Air Data / Attitude/Heading Reference System Features: + No Moving Parts - MEMS Gyro and Accelerometer Technology + No GPS Dependence + Continuous Built-In Tests Detect 99% of all possible faults including gyro bias instability + Fully Functional During Aerobatics + Gyro-Stabilized Slaved Magnetic Heading + Suitable for IFR Primary Attitude Reference Horizon AD/AHRS Dual AHRS Single AHRS Position this end toward front of aircraft The GRT Avionics AD/AHRS incorporates solid-state MEMs type angular rate sensor and accelerometers, with an external 3-axis magnetometer to provide roll, pitch, and gyro stabilized magneticheading data designed specifically for use in aircraft applications. In addition, the sensor package provides indicated airspeed, pressure altitude, and outside air temperature with the accuracy required for IFR certification. Unlike traditional spinning mass mechanical gyros, the accuracy of the attitude data is not significantly degraded by continuous circling or aerobatic flight, and “gyro lock” (attitude limits) do not exist. Accurate attitude data is maintained through aerobatic flight with no limitation other than the maximum angular rate that may be sensed by the angular rate sensor. Built-in-test functions are executed at power-up, and during continuous operation. Attitude validity is provided continuously, and automatic recovery is provided is the maximum angular rates are exceeded. In-flight alignment is allows full accuracy operation within 2 minutes after power interruptions in-flight. Dual Horizon Series I AD/AHRS Utilizing the same footprint, and only 1 ½”taller, the Dual Horizon AD/ARHS incorporated two completely independent AD/AHRS systems into one compact enclosure, providing a simple upgrade path to a dual air data/attitude heading source. 25 Pin Female D-sub Grand Rapids Technologies, Inc.
