Echo Repeating Acoustics Source System (ERAS)

Echo Repeating Acoustics Source System (ERAS) - calibration, test and performance evaluation of airborne, surface ship and submarine sonars

Chelsea Technologies Group manufactures a wide range of state of the art equipment and systems for calibration, test and general performance evaluation of airborne, surface ship and submarine sonars. The core technology has developed over a number of years and now includes the ERAS, PERS and VASS range of products. Echo Repeater Acoustics Source (ERAS) is a compact and versatile system for the performance evaluation of a wide range of active and passive sonar. It has been designed to be hand-deployed from small vessels with few facilities - the transducer assembly is a small lightweight unit containing both projector and hydrophone. At the surface, the system includes a rugged, portable, power amplifier unit and a controlling computer.

Existing users of these systems include UK QinetiQ, UK Director of Submarines, NATO SACLANT Undersea Research Centre, La Spezia, Italy, the Belgian Navy, and Exelis Inc, USA.
