HXGC-F301 integrates a 0.002°/h closed-loop fiber-optic gyroscope, high-reliability three-axis accelerometers, and a navigation computer into a single high-precision, multi-domain integrated navigation unit. It is housed in a reinforced, sealed enclosure and supports multiple communication interfaces including RS422, RS232, CAN, and Ethernet.
The system provides complete output of attitude, three-axis angular rate, acceleration, position, and time-synchronized data. It is compatible with multiple external devices including DVL, BeiDou, and depth sensors, and supports automatic switching between multiple operating modes: pure inertial, GNSS/DVL integrated, odometer-aided, and degraded-signal modes. It also includes fast alignment, self-calibration, data logging, and health monitoring functions.
