Simrad ME70 Scientific multibeam echo sounder

Bathymetric option

By adding the bathymetric application to the Simrad ME70 Scientific multibeam echo sounder you get a true dual purpose multibeam echo sounder.

The resulting system provides two main functions:

  • a scientific multibeam echo sounder with calibrated split-beams for fishery research
  • a hydrographic multibeam echo sounder system for seabed mapping

System description

When you use the bathymetric application with the ME70, a fan of beams similar to what is customary for hydrographic multibeam echo sounders is created. These beams are processed by the Bathymetric Processor Unit. This is an advanced bottom detector computer normally found in the hydrographic multibeam echo sounders provided by Kongsberg Maritime.

The soundings generated by the bottom detector computer are transferred to the Bathymetric Operator Station and the Seafloor Information System (SIS) application. This ensures compatible data with the other hydrographic multibeam echo sounders. By using the remote control features of the ME70, the Seafloor Information System (SIS) application is allowed to control the entire operation.

From an operational point of view, the user interface provided by the ME70 with the bathymetric application is identical to the interface used by the hydrographic multibeam echo sounders provided by Kongsberg Maritime.

Main units

The Bathymetric option for the Simrad ME70 comprises two units. Both units are added to the standard Simrad ME70 system. A complete mapping system will in addition require a colour display, vessel motion sensor, a heading sensor, sound velocity sensor(s) and a positioning system.
