Our EM 3000 multibeam echo sounder has been installed on a Norwegian ULA class submarine. The system will be upgraded to an EM 3002 later this year.
New navigation concept The information from the echo sounder allows the submarine to optimise navigation while submerged. The Norwegian Defence Research Establishment (FFI) is developing a new concept for underwater navigation and the data produced by the EM 3002 will play a vital part. The system is also useful when bottoming the submarine. Successful preliminary tests have been done with the EM 3000 and the users onboard are enthusiastic.
