Fiber Optic Gyro Attitude Heading Measurement System

Product Details



Features:

The fiber-optic strap-down heading attitude measurement system AHRS is composed of a closed-loop fiber optic gyroscope (the ER-AHRS-10M uses an ultra-small closed-loop fiber optic gyroscope) and a quartz flexible accelerometer as the core inertial component, which is aligned or preliminarily derived from the external input heading. The aligned attitude system is implemented by satellite signal combination correction in alignment after flight.  The product can work in pure inertial attitude state or satellite signal combined attitude state, and simultaneously output three-axis high-precision angular rate and line acceleration signals (where ER-AHRS-10 is not combined).  Flight status parameters such as aircraft attitude, heading, position, speed, acceleration, and angular velocity can be provided for cockpit display, aircraft control, radar antenna platform, and other systems.  The product has the characteristics of small size, light weight and high reliability.

Application areas: camera equipment, seekers, transport aircraft, drones, helicopters, small and medium-sized general aircraft.
