The LN-270 combines a high accuracy, integrated fiber-optic gyro (FOG), an INS, and a 12-channel P (Y) code GPS.
WebApr 1, 2012 · The AHRS typically contains three rate gyros to measure angular aircraft motion in the pitch, roll and yaw axis and three accelerometers to measure aircraft linear motion along the longitudinal, lateral and vertical axis of the aircraft. This allows the AHRS to replace six separate line replaceable units (LRUs) with one LRU.
