Main characteristics：Main features: HEC395 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
Autonomous vehicles often require precise attitude and heading information when performing complex tasks, but irregular movements can easily lead to errors, even in static environments. The HEC395 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.
HEC395 also has excellent dynamic performance, ensuring high accuracy in dynamic measurement. The high cost-effectiveness makes HEC395 very suitable for situations requiring high posture accuracy.
