System description 1 SYSTEM DESCRIPTION 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.
- Loudspeaker • Sonar room units: - Transceiver Unit - Hull Unit See figure 1 on page 3 for the SP90 system diagram. → 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.

Simrad SP90 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.
System description 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 SP90 Scientific output The Scientific Output is designed for research purposes. When activated, the following data are available on an Ethernet (LAN) output: • Beam data • Target data • Own ship data • Gear data The scientific output option does not include any storage module.
System description 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...

Simrad SP90 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.
FM Correlation filter In addition to the traditional single frequency transmitting method, the SP90 sonar is equipped with an FM correlation mode. In FM mode each transmission pulse contains up to eight different frequencies, and the receiver makes a spectrum analysis and compares the received echoes with the transmitted frequency code.
RCG filter must therefore be used with care if scattered schools are to be detected. PP Filter The SP90 sonar is equipped with a ping-to-ping filter to give a clean and steady presentation by reducing the interference and noise. This filter compares the echoes from a selected amount of transmissions (pings), and an echo has to be present in the selected amount of pings in order to be presented on the display.
In addition to log and gyro, the following peripheral equipment can be connected to the sonar. • A (D)GPS may be connected to the SP90 sonar to establish the vessels position and provide cursor and marker latitude and longitude.
Simrad SP90 2 DISPLAY MODES Introduction This chapter describes the SP90 display modes. The various modes represent the graphical presentation of sonar data. Nine different display modes are generated to present the best possible presentation and flexible choices for a large range of user applications.
Display modes Bow Up When Bow Up mode is selected, the vessel symbol is stationary on the screen with the bow pointing upwards. The echo presentation covers 360 degrees around the vessel, and all echoes are updated for every ping. The distance from the vessel symbol to the outer echo ring is equal to the selected range.
Simrad SP90 North Up When the North Up mode is selected, true north is always up on the screen. The vessel symbol is stationary with the bow pointing in the vessle’s course direction. The movement of the echoes across the screen are controlled by a combination of the vessel’s course and speed and the target’s own...
Display modes True Motion When the True Motion mode is selected, the picture is locked to a geographical position, where the vessel moves around the screen according to its present course and speed. All echoes are always presented in their correct position relative to the vessel, and their movements on the screen will be a true representation of the movements of the targets through the water.
Simrad SP90 180° / Audio When the 180° / Audio mode is selected, the upper half of the screen shows a 180 degrees bow-up presentation, while the lower part is used for a recording of the audio channel. The audio channel is shown with a continuous white line in the horizontal picture, and it can be trained in any direction.
Display modes 270° / Vertical The 270° / Vertical mode is specially designed for purse seining. The vertical half slice is displayed in the lower left corner for normal setting with the net on the starboard side. If the net is set on the port side, the 60 degrees vertical slice will be displayed in the lower right hand corner.
Simrad SP90 Bow Up / Vertical When the Bow Up / Vertical mode is selected, the picture is divided into three sections; where the left side is a bow-up presentation similar to the bow-up presentation previously described. The upper part on the right hand side is a catch data presentation, while the lower part is a 60 degree vertical slice presentation.
Display modes True Motion / Vertical When the True Motion / Vertical mode is selected, the picture is divided into three sections; where the left side is a true motion presentation similar to the true motion presentation previously described. The upper part on the right-hand side is a catch data presentation, while the lower part is a 60 degrees vertical slice presentation.
Simrad SP90 Dual 1 The Dual mode is a kind of “two sonars in one” operation, where each presentation is updated for every second transmission. All settings can be set individually for each of the two presentations. This makes the dual mode especially useful for optimizing settings by directly comparing the two presentations.
Page 33
Display modes 2.10 Dual 2 The Dual 2 mode is very similar to the Dual 1 mode previously described, but the “two sonars” are presented next to each other.. All settings can still be set individually for each of the two presentations.
Simrad SP90 3 SONAR OPERATING PANEL Introduction You may enter operational commands directly on the Sonar Operating Panel. Sonar functions may also be accessed and activated using the menu field on the display and the trackball on the operating panel.
Sonar Operating Panel Main switch Main switch functions control power to the sonar, hoisting and lowering of the transducer and indicates the transducer’s current position. MAIN SW. Power Pressing Power for approximately two seconds powers up the sonar. The adjacent green LED blinks while the Sonar Control Unit boots up, and remains illuminated once the system is operational.
