When exiting the program it is always best to close the PupAIS window first to ensure that the sub-processes are killed with it. When launching PupAIS the two windows for PopuLister and PloyPlot also pop up, and after a while any available targets start appearing. Then set the path to AISMon.log as the input file in the PupAIS source (the variable "ipf" in circa line 1280). In AISMon's configuration window, tick the "Logfile Output" box. (And, yes - snazzy app names are important!) PopuLister (AISflukt.py), shows the available information for the entire "population" of targets in radio range, one "screen" per target, while PloyPlotter (Ployplot.py) presents positional data in the form of a pseudo radar screen, graphically indicating Range, Bearing and Course for each target. This list is written to a repeatedly updated CSV file, which is then parsed by the two companion python programs:
This last step is what PupAIS is about! It generates a dynamic list of all the message emitting ships (and some other types of targets) within VHF range. The second step in the transformation is to "decapsulate" each NMEA message string in order to discover its meaningful data content, which can then be parsed and presented by a dedicated application. The latter restriction to Linux users, though, is easily overcome by running it under Wine. Unfortunately, the code is not open-source, and furthermore Windows only. !AIVDM,1,1,A,1?4Gw0QPjb1AaC8R4
