NV-AH300 attitude reference system is a product with high stability and miniaturization design, which can measure the attitude parameters (roll and pitch), heading parameters, angular velocity and acceleration information of the moving carrier. The heading, attitude and angular velocity deviations are optimally estimated by a 6-state Kalman filter with appropriate gain, which is suitable for aircraft attitude backup systems and other attitude direction measurement applications.
NV-AH300 uses a quartz flexible accelerometer and fiber optic gyroscope for high reliability and stability. The initial true heading value is measured by the magnetic north direction measured by the external anti-interference magnetic compass and the local geographic coordinates, and the gyro maintains the heading information when the carrier moves. At the same time, the product has excellent environmental characteristics, sealing design and strict process to ensure that the product can still accurately measure the angular velocity, acceleration, heading and attitude of the carrier and other motion parameters in harsh environments.
