Simrad SH90 Fish finding sonar

Processor Unit

The SH90 Processor Unit comprises a single powerful maritime computer.

Earlier versions of the Simrad SH90 sonar used a different computer. Production of this unit was stopped in August 2013. The current computer is the second generation used with the sonar.

Processor Unit

The Processor Unit serves several functions.

It performs the advanced signal processing required to present the information on the display, and it allows you to control the sonar. It provides the graphic presentation of the sonar modes and the images created, it holds the menu system, it communicates with the Transceiver Unit, and reads information from the peripheral units.

The Processor Unit is a marine computer using the Microsoft Windows® operating system.

It is designed for rugged use, and placed on shock absorbers. The computer is based on a commercial design, but the software and hardware has been specified and assembled specifically for Simrad to meet the sonar requirements.
