Error getting tarcks for aircraft

Thank you very much for the quick reply.

I had hope to put together a live demo, using software only. It looks like that won't be possible.

However, I did purchase a receiver and antenna, so will work on setting up a live data-feed using a Raspberry Pi.

Well, I would settle for the current (or recent) lat/long of aircraft approaching my chosen airport (and don't mind being limited to 10 or 2 aircraft; Any hints about which APIs to use? ).

opensky-network.org/apidoc/rest.html#limitations seems to say that I can get all vectors within the last hour (which seems like overkill, as I would then have to filter them to find those heading for y chosen airport, rather than my initial plan of finding 'planes heading for the airport, then getting data for each).

I am going step by step, so software only would be a great first step, following which I can add my own feed & then fetch data from that. Obviously, I will pipe my feed to you.

Moving (live) positions on a map are good enough. Plotting their tracks would be a bonus.

Yes, of course that is what I will do. It just seems like overkill, to get vectors for everything, when I already know (from getting icao24 of craft approaching my chosen airport), which aircraft interest me. Hence, getting the track of each of these is more efficient & consumes less bandwidth.

I guess it's not too important, as this is only step 1, pre software, and I will next use my own tracker (and feed the data to you)
