Product Introduction

The GL720 is a small IMU dynamic attitude sensor developed by RUICOM Technology using MEMS inertial measurement technology. By dynamically calculating the gyroscope angular rate signal, it can output the object's horizontal azimuth, angular rate, and body acceleration along the forward axis in real time. This product incorporates a self-developed inertial navigation algorithm, constructing a Kalman filter model to provide real-time feedback and correction of system errors, effectively suppressing divergence and significantly reducing the impact of short-term gyroscope drift on measurement accuracy.

Designed specifically for applications such as robot vehicle, AGV (Automated Guided Vehicle) orientation guidance, and Model Aircraft Attitude Control, this product overcomes the limitations of traditional magnetic guidance methods that require laying magnetic strips. It eliminates the need for deploying a large number of magnetic strips on the site, making it an ideal navigation component for next-generation robots to achieve automatic line-following navigation.
