I’ve been experimenting with PlanePlotter, acarsdec and a bunch of other things recently, and have had to hack my way to a whole new level of incompetence with Linux in the form of Raspbian.
One important thing I just learned was the system flow diagram for dump1090 and piaware.

At least now I understand better how messages flow within my setup here, and am starting to learn more about the different ports on dump1090 and piaware, and how mlat (multilateration) works using the aggregation of other piaware receivers through the FlightAware servers.
PlanePlotter, however, is a whole new can of worms, perhaps interesting worms, but worms, nonetheless.
