WebUltra-Short Baseline positioning system, which can work in the full ocean depth, has not yet been available in any commercial companies. In recent years, the development of underwater submersibles, such as 11,000-meter human occupied vehicle, 11,000-meter underwater remote-control vehicle and autonomous underwater vehicle, has been carried … USBL (ultra-short baseline, also known as SSBL for super short base line) is a method of underwater acoustic positioning. A USBL system consists of a transceiver, which is mounted on a pole under a ship, and a transponder or responder on the seafloor, on a towfish, or on an ROV. A computer, or "topside unit", is used to … See more An acoustic pulse is transmitted by the transceiver and detected by the subsea transponder, which replies with its own acoustic pulse. This return pulse is detected by the shipboard transceiver. The time from the … See more USBLs are used in "inverted" (iUSBL) configurations, with the transceiver mounted on an autonomous underwater vehicle, … See more • Product Survey USBL Systems Hydro International, May 2008 • Coxworth, Ben (2024-04-07).

Web28 Dec 2024 · The ultra-short baseline underwater positioning is one of the most widely applied methods in underwater positioning and navigation due to its simplicity, efficiency, low cost, and accuracy. A short baseline (SBL) acoustic positioning system is one of three broad classes of underwater acoustic positioning systems that are used to track underwater vehicles and divers. The other two classes are ultra short baseline systems (USBL) and long baseline systems (LBL). Like USBL systems, SBL systems do not require any seafloor mounted transponders or equipment and …
