Scout calculates the position of a subsea target by measuring the range and bearing from a vessel mounted transceiver to a small acoustic transponder fitted to the target; a technique known as Ultra-Short BaseLine (USBL) positioning. USBL positioning is widely used by the offshore and oceanographic industries as it offers high accuracy performance combined with ease of operation. One of its main advantages is that no other in-water acoustic equipment has to be deployed before underwater operations can commence. Only the targets being tracked need to be equipped with a transponder. |

Sonardyne USBL Positioning System | The USBL acoustic positioning method involves measuring the range and bearing from a vessel based transceiver to a single, subsea transponder. The seabed transponder which may be mounted on a mobile target such as a ROV, or on a fixed target such as a seismic cable ground station, is initially positioned using data from the ship's GPS. The USBL system then provides a range and bearing estimate of the transponder relative to the ship's position. |
