Introduction to Inertial Navigation System Products
Autonomous vehicles often require precise heading information when performing complex tasks, but irregular movements can easily lead to errors, even in static environments.
The HEC295 9-axis attitude heading reference system is an inertial product specially designed by Huilian Technology to provide high-precision roll, pitch, and azimuth measurements for dynamic motion environments. The product includes 9 degrees of freedom sensors, 3 acceleration sensors, 3 magnetic sensors, and 3 gyroscopes. By optimizing the extended Kalman filter algorithm, the high accuracy of dynamic measurement is ensured. The high cost-effectiveness makes HEC295 very suitable for situations requiring high heading accuracy.
