Simrad SP90
Low frequency long range fishery sonar
Software version V1.1.XX
WARNING
The sonar must never be powered up when the ship is
in dry dock. The transducer will be damaged if it
transmits in open air. To prevent inadvertent use of the
sonar, set switch S102 at the rear side of the Sonar
processor Unit to Off whenever the vessel is in dry dock.

1 SYSTEM DESCRIPTION
1.1 Introduction
The Simrad SP90 sonar is a long range omnidirectional low
frequency sonar, designed for medium and large sized fishing
vessels, preferably for purse seiners. The standard frequency is 26
kHz (triple and multiple frequencies as option), and the beam can
be electronically tilted from +10 to –60 degrees.
Great emphasis has been placed on giving the best possible
presentations on a high resolution colour display. The processor
unit is controlled by Microsoft’s Windows 2000operating
system, which result in a flexible choice of display modes for a
large range of user applications.
The signal processing and beamforming is performed in a fast
digital signal processing system using the full dynamic range of the
signals. In addition to the traditional single frequency transceiver
system, the SP90 sonar contains an advanced frequency modulated
filter system (FM).
The cylindrical multi-element transducer allows the
omni-directional sonar beam to be tilted electronically down to -60
degrees. This allows you to automatically track schools of fish, and
to observe the whole water volume around the vessel. An optional
stabilization system is available for electronic pitch and roll
compensation.
This chapter covers the following subjects:

→Options, page 5.
→Functional description, page 7.

1.2 System overview
Main units
The Simrad SP90 sonar consists of the following units:
•Wheelhouse units:
- Display monitor
- Sonar Operating Panel
- Processor Unit
- Loudspeaker
•Sonar room units:
- Transceiver Unit
- Hull Unit
→Seefigure1onpage3fortheSP90systemdiagram.
Wheelhouse units
The Display Monitor is normally a 18” or 20” high-resolution
colour LCD (Liquid Crystal Display). In addition to the sonar
picture, the monitor can also display the user menu for the
interactive operation. In order to ease the situation comprehension,
certain colours have been chosen to better the distinction between
the various elements in the scene.
The Operating Panel contains all necessary control functions for
operating the sonar. The controls are arranged in function groups,
which gives a clear and easy operation. Note that all sonar
operation also may be made from the roller ball, or from an
optional remote standard mouse.
The Processor Unit contains a ruggedized computer with
interface for the auxiliary equipment (log, gyro, GPS, echo
sounder, trawl systems, purse seine systems etc.). The processor
unit runs the Microsoft Windows 2000operating system,
modified by Simrad to suit the SP90 sonar requirements. One
signal cable is used for the communication with the Transceiver
Unit in the sonar room.
The Loudspeaker reproduces the audio of the echoes for the
selected audio channel.

Sonar room units
The Transceiver Unit is located in the sonar room, close to the
Hull Unit. One signal cable is used for communication with the
Processor Unit in the wheelhouse. The transceiver performs the
signal processing and the digital beamforming of the 256
transmitters and 256 receiver channels, which are located on the
eight identical transceiver boards.
The standard Hull Unit is designed to be lowered 1.2 meters below
the ship’s hull. (An optional hull unit will lower the transducer to
1,6 meters below the hull.) The transducer can also be lowered to
any selectable middle position. Note that in case of voltage failure,
the Hull Unit can be manually raised or lowered by means of a hand
crank.
The cylindrical 256-elements transducer allows the sonar beam
to give full 360 degrees coverage of the water volume down to -60
degrees.
The optional sensor for the electronic stabilization of the sonar
beams is housed in the motor control unit which is mounted on the
Hull Unit.
WARNING If the transducer hits larger objects or bottom, the transducer
shaft may be bent, or in worst case it can be broken off. A
broken transducer shaft will cause water leakage in the top of
the shaft. To prevent larger leakages in such a case, do not raise
the transducer shaft to the upper position. To prevent serious
damages it is therefore of great importance to have a good
pump and warning system in the sonar room.

1.3 Options
General
The standard SP90 is a single 26 kHz version with maximum 60
degrees tilt, and without beam stabilization.
Note that the options described below are pre-programmed into the
standard version. A code word is required to make the actual option
available. Simrad offers a 1 month free test period for each option.
→To enter the code words, refer to the procedure on page 49.
For a permanent installation of any of the option, a new code word
will be released when ordering the option.
Stabilization system
When the optional beam stabilizer is activated, both horizontal and
vertical beams will be stabilized electronically for roll and pitch
movements up to ±20 degrees. The beam direction will then
change continuously according to the vessel’s movements, and
secure an optimal contact with the targets even in rough seas.
Figure 2 Optional stabilization system
Triple- or multiple-frequency
In addition to the standard 26 kHz frequency, options are available
for triple and multiple frequencies.
•In the triple-frequency version, you can select between 24 kHz,
26 kHz and 28 kHz.
•In the multiple-frequency version you can select from 11
frequenciesfrom20to30kHzin1kHzsteps.
These selections are particulary useful when it is necessary to
suppress interference from other sonars.

1.4 Functional description
Introduction
The basic principles of the SP90 sonar are unique because of the
256 separate transmitter and receiver channels with their
transducer elements spread around on the cylindrical transducer
array.
The transmission, reception and data processing are under
computer control, and the powerful capabilities of the sonar are the
results of sophisticated digital signal processing software and state
of the art hardware.
Functional principles
When the Omni beam is tilted, the total beam picture can be
compared with folding an umbrella, which means that all beams
in 360 degrees around the vessel have the same tilt angle.
Figure 3 Omni beam
The beam can be tilted from +10 up to -60 degrees down.
In addition to seeing the target from above, it is also possible to see
the target from the side, by using the vertical slice presentation. In
this case the beam covers a continuous vertical beam from 0 to -60
degrees in one transmission.

Figure 4 60 degrees vertical slice
This vertical slice, which is presented by the white audio line in the
horizontal picture, can be selected to any bearing by the manual
training control. The combination of the Omni mode and the
vertical slice will give an optimal visualization of the catch
situation.
