Calculations for the Positioning System

When configuring the positioning system on the system web page (Scala2 receiver page), you must consider the position of the hydrophones. When they are misaligned, you can calculate their misalignment angle with the following calculations.

Tip: A spreadsheet is available on the Useful Resources page of Marport support website to help you complete this page.
Note: Baseline length is the distance between two hydrophones. It must be in meters.
The misalignment angle (angular offset around Z axis) is calculated with the following formula:

Sign of Angles

You need to add a negative sign (-) to the result if the starboard hydrophone is placed further aft. The sign of the angles is important to receive correct positioning data.





Negative sign (-) Positive sign (+)
