Cerulean USBL Receiver and Transmitters with Auto Sync function
Streamline underwater positioning with this advanced USBL system featuring integrated Auto Sync technology. Designed for ROV tracking up to 300m deep, it delivers real-time location data directly to QGround Control maps with 0.1° angular resolution. By utilizing GNSS signals for background calibration, it eliminates manual startup delays and reduces slant range error accumulation to just 0.5m per hour for professional-grade subsea navigation.
