The KONGSBERG 125-218494 is an EM 3002 Single Unit Processing Unit designed for the Kongsberg EM 3002 multibeam echo sounder system. The Processing Unit performs beamforming and bottom detection, controls sonar-head functions such as gain and ping rate, and provides interfaces for external positioning, attitude, heading, clock, tide, and sound-speed data. The EM 3002 Processing Unit is designed for integration with the operator station and sonar head in hydrographic surveying and seabed mapping applications.
The EM 3002 system operates around 300 kHz and can be configured with one or two sonar heads. The Processing Unit uses a 19-inch rack-mountable 4U instrument format and communicates with the operator station through Ethernet.
