System description 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. Great emphasis has been placed on giving the best possible presentations on a high resolution colour display.
Simrad SP90 System overview Main units The Simrad SP90 sonar consists of the following units: • Wheelhouse units: - Display monitor - Sonar Operating Panel - Sonar Processor Unit - Sonar Interface Unit - Loudspeaker • Sonar room units: - Transceiver Unit - Hull Unit Wheelhouse units The Display Monitor is a 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.
System description 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 Sonar Interface 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.

Simrad SP90 Options General The standard SP90 is a single 26 kHz version with maximum 60 degrees tilt, and with beam stabilization. The beam stabilization was an optional function until 1 January 2003. After that date, the function was included with the standard sonar delivery. The options described below are pre-programmed into the standard software version, and a code word is required to make the actual option available. Simrad offers a 1 month free test period for certain options.
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 computer control, and the powerful capabilities of the sonar are the results of sophisticated digital signal processing software and state of the art hardware.
Simrad SP90 60 degrees vertical slice Omni/Vertical combination In addition to the Omni picture, the vertical slice is especially useful for visualizing the vertical distribution of a school of fish. In that way, it is not necessary to go over the target to see the distribution on the echo sounder, which often results in a spreading of the school. 8 850-164511 / Rev.
System description Stabilization system When the 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. Stabilization system Reception A great effort has been made to reduce unwanted noise to get a clean and stable echo presentation.
Simrad SP90 However, the sound absorption in salt water increases with the frequency, thus giving the lower frequencies a longer detection range. AGC (Automatic Gain Control) This control will automatically adjust the gain in the preamplifiers depending on the strength of the incoming echo signals. The strength of the filter can be selected in the menu. Note that the AGC senses the echo strength in five fixed directions, and use this as a basis for adjusting all the receiver beams.
System description There are 256 separate transmitters in the unit distributed on eight transceiver circuit boards. Each transmitter is individually addressed and controlled from the signal processor. The controlled parameters include power output and time delay for each transducer element in order to form a beam with the selected tilt angle. When the stabilisation system is active, the tilt angle for each beam will automatically be corrected relative to the vessel’s pitch and roll movements.
Simrad SP90 Peripheral equipment The SP90 sonar requires connection to a speed log and a course gyro. An inaccurate log or gyro input will cause inaccurate indication of the vessel and target movements. 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.
Display modes DISPLAY MODES Introduction This chapter describes the SP90 display modes. The various modes represent the graphical presentation of sonar data. Several display modes are available to present the best possible presentations as well as flexible choices for a large range of user applications.
Simrad SP90 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. 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 movements.
Display modes 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 movements. Related topics → 850-164511 / Rev.
Simrad SP90 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.
Display modes 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. The recorded echoes are a direct replica of the echoes under the white audio line.
Simrad SP90 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. With this presentation, it is easy to keep the best contact with a school in both the vertical and horizontal presentation, and to determine its size distribution.
Display modes 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. Related topics → 850-164511 / Rev.
Simrad SP90 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. Related topics → 20 Cosmetics, page 52 850-164511 / Rev.
Display modes Bow Up / Dual Vertical When the Bow Up/Dual Vertical mode is selected, the upper part of the screen shows a curtailed bow-up presentation, while the lower part shows two vertical slice presentations. The bearing of the left vertical presentation is indicated by the white audio line in the horizontal presentation, while the bearing of the right vertical presentation is indicated by the yellow-dashed line.
Simrad SP90 Bow Up / 180 Vertical When the Bow Up/180° Vertical mode is selected, the upper part of the screen shows a curtailed bow-up presentation, while the lower part shows a 180 degrees vertical slice presentation. This mode is mainly intended for trawlers, where the vertical view acts as a multi-beam echo sounder. The bearing of the vertical slice can be selected in the Vertical View menu.
Display modes Dual 1 The Dual 1 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. To optimize the horizontal settings, use the Horizontal menu to try different settings in the upper picture. These settings are automatically transferred to the other modes.
Simrad SP90 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. Related topics → 24 Cosmetics, page 52 850-164511 / Rev.

On-board maintenance Wheelhouse units Cleaning The units must be kept clean and dry. Remove salt water residue with a soft cloth moistened in fresh water. Do not use strong solvents. Note The display screen must be handled with care to avoid damage to the anti-glare filter coating. Use a soft cloth without any strong solvents when cleaning it. Dust filter To avoid overheating, the dust filter(s) must be inspected, and if necessary, cleaned once every third month.
Simrad SP90 MC70 Sonar Processor Unit The two dust filters on the MC70 are located on the air inlets on the front side of the Sonar Processor Unit. Figure 8 The dust filters on the MC70 Sonar Processor Unit (CD7023) The filter is accessible by simply pulling off the filter grid. Each filter should be vacuum cleaned, or washed in soap and water. If washed, the filter must be dried thoroughly before being reinstalled. 158 850-164511 / Rev.
On-board maintenance Transceiver Unit Dust filter There is a dust filter in the bottom of the Transceiver Unit. To avoid overheating, this must be inspected, and if necessary, cleaned once every third month. The dust filter is accessible from the outside of the Transceiver Unit, by unscrewing the eight finger nuts in the bottom of the unit. The filter should be vacuum cleaned, or washed in soap and water. If washed, the filter must be dried thoroughly before being reinstalled.
Simrad SP90 Hull unit General The sonar hull unit must be under continuous watch as a part of the vessel’s machinery. As the hull unit may be exposed to severe strain because of pitching and vibrations, it must be inspected regulary for loose parts. In addition to lubrication, check for signs of corrosion. If required, clean the corroded areas and paint over with a high quality protective paint.

Simrad SP90 Docking the vessel When docking the vessel, great care must be taken not to damage the sonar trunk and protecting blister. 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, disconnect the mains plug on the Sonar Processor Unit whenever the vessel is in dry dock. Figure 10 The location of S302 in the Motor Control Unit 162 850-164511 / Rev.
On-board maintenance On vessels which have been in dock, the Hull Unit must be thoroughly examined, and the hoist/lower functions must be checked out and observed while operating the Hoist/Lower Switch (S302 in the Motor Control Unit). The hoist/lower motor will automatically stop when the transducer shaft reaches the upper or lower limit switch. Remember to set the hoisting/lowering switch back to Remote for normal operation. 850-164511 / Rev.
Simrad SP90 Cleaning the transducer The transducer normally needs little attention. However, the transducer face should be inspected and cleaned whenever the vessel is in dock. To lower the transducer when in dock, use the hoist/lower switch S302 in the Motor Control Unit (mounted on the gantry). Set the switch to STOP to position the transducer at any vertical location. Do not use strong solvents, but a normal synthetic soap and water.
On-board maintenance Hoist motor overload protection To prevent the hoist/lower motor from overload, an overload circuit breaker S301 is located in the Motor Control Unit. This may automatically be switched off during hoisting if the vessel’s speed is too high, or if the transducer shaft has been bent. To reset the motor overload switch, open the Motor Control Unit, locate the switch S301 and press the button marked 1. Figure 11 The location of S301 in the Motor Control Unit 850-164511 / Rev.
Simrad SP90 Emergency hoisting and lowering In case of a failure or an emergency in the normal hoist/lower operation controlled from the Sonar Operating Panel, the transducer may be hoisted and lowered from the Sonar Room. Local control switch S302 If the 3-phase voltage for the hoist/lower motor and the +24 Vdc stand-by voltage from the Transceiver Unit are available, the transducer can be hoisted or lowered by means of switch S302 in the Motor Control Unit.
On-board maintenance 850-164511 / Rev.E 7. Remove the hand crank from the stub shaft, and mount it in its storage position in the Motor Control Unit. 8. Press the black button marked 1 on the motor overload switch S301.
Simrad SP90 Air bleeding To avoid damage to the transducer by transmitting in air inside the trunk, the air bleeding system must be checked after the ship has been docked. Observe the following procedure. 168 1. Close the air bleeding cock on top of the trunk flange and dismount the pipe. 2. Open the air bleeding cock and check that the water is passing freely through the cock. 3. Check that the pipe is open by blowing in one of the pipe terminations. 4.
On-board maintenance Lubrication From the factory, the hull unit is lubricated with the types of oil or grease as specified below. However, if of equal quality, other types may be used. The following number refer to the lubrication points on the illustration to the left. (1) The ball bearing on each end of the hoist/lower screw must be lubricated with normal ball bearing grease. (2) The hoisting spindle should be lubricated with Tonna Slideway Oils S68.
