Land FOG INS (Merak-L03)
The vehicle-mounted optical gyroscope positioning and orientation equipment uses laser or fiber optic gyroscope and quartz accelerometer as the core sensors, adopts strapdown technology system, runs advanced navigation software, and outputs navigation information in real time. This series of products has a variety of working modes such as zero-speed correction, inertial/satellite guidance combination, inertial/odometer combination, etc., which can provide users with full-parameter navigation information of carriers and meet the needs of various vehicle platforms.
