    Get a basic knowledge of the sensor. Introduction Marport's Speed Navigator is a high-definition net sounder, designed to operate on the trawl headline and tunnel. It measures the speed of the water flow in two axis: the flow along the direction of the trawl and across it.

  • Page 7: Applications

    Applications Examples of data received and displayed in Scala2 application. Below is an example of data received from the sensor. The autorange mode is activated, so the sounding range changes to 20, then 10 meters as the sea bottom gets closer. See About the Automatic Range Mode (on page 27) for more details about this mode.

  • Page 29: Calibrating The Sensor For Target Strength

    See Configuring the Echo Sounder (on page 25) for details about Mosa2 settings. Calibrating the Sensor for Target Strength Value You need to calibrate the sensor to offset the variability of the sensor transducer and of sound transmission. The aim is to have all sensors displaying the same target strength value (echogram color) for a given target.
  • Page 30 2. Before putting the sensor in water, connect the cable extension to the bottle. 3. Connect the Configuration Cable or a Dock charger plug to the other end of the cable extension. If applicable, connect the Configuration Cable to the computer. Notice: The Configuration Cable and charger plugs are not waterproof: do not immerse them.
  • Page 31 10. Make sure Disable Waterswitch is activated. This prevents the sensor from switching into running mode when the endcap is wet or immersed. 11. Now you can put the sensor into water. Calibrating the Sensor in Mosa2 1. By default, the Distance from sensor to the target (cm) is 50 cm and the Expected target strength (dB) is -39 dB (target strength value of a ping pong ball of 39 mm diameter).
  • Page 32 3. From the bottom of the screen, click Send ping to send one ping that will identify the distance to the target. A curve is displayed. Click anywhere on the graph to show the green markers. The horizontal line indicates the target strength and the vertical line indicates the distance.
  • Page 33 A new target strength offset is calculated. 5. Accept the new calibration settings suggested in the dialog box. The gain correction is auto-populated. Speed Navigator | V1 | Sensor Configuration...

  • Page 34: Calibrating The Speed

    The sensor sends 1 ping to check if the calibration settings are correct in comparison to the target strength set (e.g. -39 dB). If they are correct, calibration settings are saved. If calibration settings are not correct, check the installation in the water tank. Then restart the calibration procedure.
  • Page 35 When the sensor is in water without any current, it must measure ± 0.1 knot max. for along and across speeds. But because of the variability of the sensor components, it may still measure higher levels of speed. The aim of calibration is to apply an offset so that the sensor measures the correct speeds.

  • Page 36: Tester

    Mosa2 calculates the offset, applies it to the sensor and the sensor sends again measures with the offset applied. 8. Marport offices only: Save the configuration file and add it to the sensor page in MASP, in Attachments > Miscellaneous.
  • Page 37 If you do not have the EM Log tester, please refer to your local Marport sales office. The EM Log tester is also useful to check that the sensor is still operational over time. You can check speed before every fishing campaign to make sure the sensor works properly.

  • Page 38: Applying Offsets To Measurements

    4. Click EMlog Test. The along speed must be between 2 and 3 knots for a standard installation (1.10 Along Gain) and 2.5 to 3.8 for a reversed installation (1.26 Across Gain), and the across speed must be between -3 and -2 knots. Troubleshooting: If the along speed is negative and the across speed positive, it means that you placed the EM Log tester upside down.
  • Page 39 1. Go to Measurements page and click next to depth or temperature to apply offsets. 2. Enter a target value. Click The measured value becomes the same as the target value. The value of the offset is displayed. 3. If you need to reuse offsets from a previous configuration, click then select the configuration file (*.A2C).

  • Page 40: Testing Measures

    Testing Measures You can test the measures taken by the sensor (e.g. battery level, temperature, depth) to check that there are no faults. You can test the sensor in water or in air. In air, the following measures will be wrong: height, conductivity.

  • Page 61: Installation

    Make sure to always use a protective cage when using the sensor. The protective cage must be approved by Marport. Any additional protective devices installed in front of the head may disrupt the flow and therefore alter the water speed measurements.
  • Page 62 When the sensor is installed on the headrope, you may not see the footrope. If you want to see it, move back the sensor of a few meters. The sensor must be placed in a way that there is less than +/- 5 degrees of pitch and roll. You may need to add floats to the back of the sensor to achieve this.
  • Page 63 Reversed Installation In this installation, the EM log pins face up instead of down. In this case, the Speed Navigator is installed on a board to provide more stability. The aim of this installation is to prevent the EM log pins and transducer to hit the deck when the trawl is hauled. 1.

    • Make sure the three pins are fully inserted inside the sensor. Mosa2 does not automatically open when connecting the Configuration Cable. • Check that you see Marport Captain icon in the desktop taskbar. If you do not see it: close, then open Mosa2. The icon should appear in the taskbar.

  • Page 74: The Echogram Has A Lot Of Interference

    • Disconnect both USB connector and three-pin plug. Then, connect again the Configuration Cable. If the message is still displayed, it means there is an issue with the sensor’s components. Contact Marport support. The echogram has a lot of interference There are interference from environmental noise or other equipment such as echosounders.

    You can create a table with a list of frequencies and complete it when you add sensors. Frequencies and intervals The diagrams below show the bandwidth of the different types of Marport sensors and intervals you must respect when adding other sensors. Figure 1. PRP sensors (e.g. Catch sensor, Trawl Speed, Spread sensor...) Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.9-40kHz and 40-40.1kHz.
  • Page 79 Figure 3. NBTE sensors (e.g. Speed Explorer, Trawl Explorer, Catch Explorer, Catch Navigator, Door Sounder) Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz and 40-40.6kHz. Figure 4. HDTE narrow band mode Example: If the frequency of the sensor is 40kHz, there should be no sensors between 39.8-40kHz and 40-41kHz.
  • Page 80 Examples of frequency allocations • We recommend to allocate frequencies between 34 and 56 kHz for wideband hydrophones and between 41 kHz and 44 kHz for narrowband hydrophones. • Echosounders are usually placed around 38 kHz, make sure to allow enough distance with them.
