The airgun display configuration dialog is accessed from the Display>AIS Ship Reporting>Display Options... menu command.
The two pieces of information required to correctly position the guns are
The Source Vessel Identification
This is either the vessel PAMGUARD is running on, in which case
the gun position will be relative to the GPS receiver plugged into PAMGUARD, or it can be
another vessel in which case the guns' positions will be calculated relative to the
GPS receiver feeding the AIS transponder on that vessel. If the guns are on another vessel, you will need to know the vessel's
Maritime Mobile Service Identity (MMSI) number and input it to the
AIS Display dialog. You can get this either from the AIS data listed within
PAMGUARD, or ask the vessel's captain.
The location of the airgun array
This is in the form of two coordinates relative to the GPS receiver feeding
PAMGUARD or the GPS receiver feeding the AIS transponder on a different vessel.
You may also enter a mitigation zone, which is a simple circle of fixed radius around the airgun location.
You may also enter a predicted mitigation zone which will display the area on the PAMGUARD
map which will fall within the mitigation zone within the specified time period.
