Maritime RLG INS(Dubhe-M4)
The laser gyro inertial navigation system takes laser gyro and quartz accelerometer as its core sensors. Its high accuracy is based on the strapdown technology, coupled with the advanced navigation calculation software that outputs navigation information in real-time. This series of products has a variety of operating modes, such as the Inertial and satellite navigation combination, Inertial autonomous navigation and so on. These products uniquely address the demands for verity types of vessels platform, providing very accurate heading, roll, pitch, speed and position information.
