Simrad is a division of Kongsberg Maritime AS. For more than sixty years, Simrad has developed and

manufactured professional sonar systems for the world’s most sophisticated shing vessels. Our sonar systems are

also extensively used by several nation’s coast guards and naval patrol vessels.

The Simrad SX90 is an “off the

shelf” commercial sonar. Due to the

low price and short delivery time, the

SX90 sonar has quickly become an

alternative to high cost naval sonars.

transceiver requires a minimum of

space in the sonar room, and can

be adapted to most existing sonar

installation trunks.

The installation is simple, and

may be done in a matter of hours.

The hull unit and transceiver are

installed in the sonar room, while the

operating panel and the processor

unit are installed in the operation

synchronized from the GPS.

The SX90 is designed for

operation in shallow waters where

The SX90 ts the requirements

for advanced, compact, ship mounted

sonar systems for use in Surveillance,

ASW and other support roles in

shallow or deep waters.

Our modern sonar technology

provides features and functions

required for both small and large ship

The transducer element is designed

for maximum performance from 20

kHz to 30 kHz and each of the 256

elements is connected to its own

transmitter and receiver. You can

choose from three different vertical

beam widths, single or dual vertical

view and 180° tiltable vertical view.
