RLG INS(Dubhe-M1)

This navigation system relies on laser gyros and quartz accelerometers for ultra-precise motion sensing. Thanks to strapdown technology and smart software, it processes data instantly and supports different modes (e.g., combined GPS/inertial or purely inertial navigation). Designed for ships and marine applications, it delivers real-time updates on direction, tilt, speed, and position with outstanding reliability.
