    The settings you configure here depend on the type of sensor you have. Refer to your sensor's user guide to know the recommended settings. Note: Before you add the sensor to the receiver via Scala, it must be configured with Mosa2 software. Settings configured in Mosa2 need to be the same here (e.g. frequency, sounding range).

  • Page 29: Configuring Trawl Positioning System

    Scala | V7 | System Configuration Configuring Trawl Positioning System When you have a system with door spread sensors with position data or slant ranges, you need to complete the positioning page to get accurate measurements of the door positioning.

  • Page 30: Calculations For Positioning System

    There are two misalignment angles that you should calculate. Misalignment Z is the more critical for correct positioning data. Make sure these calculations are correct if you enter them in Scala. The drawings below show the misalignment angles and how to calculate them:...
  • Page 31 Scala | V7 | System Configuration Once you have calculated X and Z misalignment angles from the above formulas, you need to add a positive or negative sign to the result. The sign depends on the offset of the hydrophones. Refer to the drawings below to know if you need to add a negative or positive sign to misalignment Z and X.
