Underwater Positioning System

The Underwater Positioning System is a specialized technology used for tracking and locating underwater targets. It is widely applied in oceanographic research, seabed mapping, ROV/AUV operations, and underwater construction. The system typically includes acoustic positioning methods such as Ultra-Short Baseline (USBL), Short Baseline (SBL), and Long Baseline (LBL). By transmitting sound waves between underwater transponders and ship-based receivers, it calculates the relative position of targets underwater. This system can integrate depth, tilt, and GPS sensor data to improve positioning accuracy and real-time responsiveness, making it an essential tool for high-precision underwater operations.
