Question 1

What is tar1090?

Accepted Answer

tar1090 is a live, self-hosted flight-tracking map. It plots aircraft in your area in real time — like Flightradar24 or FlightAware, but on your own server and fed by signals you receive directly rather than a commercial service. Aircraft broadcast their position over ADS-B on 1090 MHz, and tar1090 displays the decoded signals as an interactive map with flight paths, altitude, and speed. This install runs it on port 8316.

Question 2

Do I need special hardware?

Accepted Answer

Yes — this is the defining requirement. tar1090 does not pull flight data from the internet; it displays signals you receive locally, so it needs an RTL-SDR (software-defined radio) USB dongle with an antenna physically plugged into the machine. The deployment passes that USB device through to the container to decode the 1090 MHz ADS-B broadcasts. Without the dongle connected, there are no signals to decode and the map stays empty.

Question 3

Which port does it use?

Accepted Answer

tar1090 serves its map on host port 8316, mapped from the container's internal port 80, so you open http://your-server:8316 in a browser. The data it shows is public ADS-B broadcasts, so sensitivity is low, but if you expose the map beyond your LAN you should still front it with TLS. The more important part of this setup is the USB passthrough for the RTL-SDR dongle, not the network port.

Question 4

Where does the flight data come from?

Accepted Answer

From the air, directly. Aircraft continuously transmit their position, altitude, and identity over ADS-B on 1090 MHz, and your RTL-SDR dongle and antenna receive those broadcasts locally. tar1090 decodes and plots them. That is the whole point — it is your own reception, not an internet feed, so what you see depends on what your antenna can physically hear, which varies with its placement, height, and the obstructions around you.

Question 5

How do I get better range?

Accepted Answer

Range depends almost entirely on your antenna: its quality, how high it is, and how clear its view of the sky is. An antenna placed outdoors and up high with an unobstructed horizon will hear aircraft far further than one sitting indoors on a desk. Good coax cable and a filter can help too. Because ADS-B is line-of-sight at 1090 MHz, elevation and a clear view matter more than anything, so improving antenna placement is the main way to extend how many aircraft you see.
