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.
Before you begin
• Door sensors are already added and configured.
Procedure
1.
From the left side of the screen where the system is displayed, click Positioning.
The positioning configuration page appears.
2.
In the Baseline part, enter the baseline and misalignment measurements:
a)
For the baseline, indicate the distance between the two receiving hydrophones.
b)
You can complete the misalignment X and Z, for more accurate positioning. See Calculations
for Positioning System on page 29. Otherwise, you can enter 0.
c)
Enter 0 for the misalignment Y.
Note: Baseline is very important to have accurate positions of the doors.
3.
In Lever Arm group, leave 0 in the fields.
4.
In Inputs group, enter the port and starboard hydrophones, according to the hydrophone
configuration.
