Main characteristics：Main features: Unmanned carrier vehicles often need accurate heading information when performing complex tasks, but the irregular movement process is easy to lead to errors, even in static environment. HEC495 9-axis attitude and heading reference system is an inertial product specially designed by Huilian Technology to provide high-precision pitch, roll and azimuth measurement for dynamic motion environment.
Product Introduction of Attitude Reference System
Autonomous vehicles often require precise heading information when performing complex tasks, but irregular movements can easily lead to errors, even in static environments.
The HEC495 9-axis attitude heading reference system is an inertial product specially designed by Huilian Technology to provide high-precision pitch, roll, and azimuth measurements for dynamic motion environments. This product includes 9 degrees of freedom sensors: 3 acceleration sensors, 3 magnetic sensors, and 3 gyroscopes. By optimizing the extended Kalman filter algorithm, the product outputs high-precision attitude information in real-time. HEC495 also has excellent dynamic performance, ensuring high accuracy in dynamic measurement. The high cost-effectiveness makes HEC495 very suitable for situations requiring high heading accuracy.
