SIMRAD SX90
Simrad high denition sonars will provide a 360 degrees picture of the immediate surroundings
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.
The SX90 comes with a choice of
three different hull units capable
of handling vessel speeds up to 24
knots, or it may be supplied for xed
installation in a streamlined dome.
The compact hull unit and
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
room. A commercial display can be
used. The only required interfaces
for the sonar are information from
GPS and Gyro. Speed log and motion
reference (MRU) inputs are optional.
The sonar’s internal clock can be
synchronized from the GPS.
The SX90 is designed for
operation in shallow waters where
This screen capture shows the sonar echoes using a reector target
with TS=-15 dB at 20 meters depth, bottom at 140 meters
Wreck detection at 4500 meters: This screen
capture shows a long range detection of a sunken
35.000 ton cargo vessel. You can see it at 10° port side,
it is marked with target tracking triangle. The wreck
lays at about 100 meters depth. The other echoes are
shallow banks in the area. The sonar is operated at
23 kHz using “FM Auto” and “Narrow Beam”. The
position of the vessel and time and date is indicated in
the lower right hand corner of the presentation.
sonar conditions are difcult due to
temperature layers, bottom or other
conditions.
Typical applications include:
• Coastal patrol
• Anti submarine warfare
• Navigation and obstacle avoidance
• Diver monitoring
• Underwater ROV and AUV
positioning
• Submarine rescue
• Iceberg detection
• Whale detection
