TDF71A Airborne Optical Gyro-Inertial Navigation

The vehicle-mounted optical gyro positioning and orientation device uses laser or fiber optic gyros and quartz accelerometers as core sensors. It employs a strapdown inertial navigation system architecture and runs advanced navigation software to provide real-time navigation information. The product series features multiple operating modes, including zero-velocity update (ZUPT), inertial/satellite-based integrated navigation, and inertial/odometer integrated navigation. It provides users with complete navigation parameters for the vehicle, meeting the needs of various vehicle-mounted platforms.
