Introduction
The TD-AH50 heading and attitude reference system product is a low-cost inertial measurement device that can measure the attitude parameters (roll and pitch), angular velocity, acceleration information and heading angle of the moving carrier. The attitude and angular velocity deviation are estimated by the 6-state Kalman filter with appropriate gain, which is suitable for dynamic measurement of navigation and positioning. TD-AH50 uses industrial-grade MEMS accelerometers, gyroscopes and magnetometers, and uses algorithms to ensure measurement accuracy. At the same time, the sealing design and strict process ensure that the product can accurately measure the angular velocity, acceleration, and attitude of the carrier in harsh environment. Through various compensations such as nonlinear compensation, quadrature compensation, temperature compensation and drift compensation, the error source of TD-AH50 can be greatly eliminated and the product accuracy level can be improved. TD-AH50 has a digital interface, which can be easily integrated into the user's system.
