The key tool we need is called dump1090 and can be found on GitHub. My Raspbian build runs only ntpd, sshd and dhcp client on the ethernet port - all other services are turned off. One of the reasons was that I had a spare 2GB SD card and these days stock Raspbian comes as 4GB image.

Raspbian - minimal version, actually custom install instead of ready made image I could download.R820T - covers from 24MHz to 1766MHz (this is the one I use).There is several main lines of those receivers (different chipsets, different capabilities - see here for comparison) but I found the two below to be the most common: Right now it turned out you can get a cheap (but also fairly basic) SDR for about £8. SDR Receiver - When Software Defined Radios started showing up I wanted to buy one but the prices were out of my reach back then.Mine never made it above 2W, so that would be something like ~£0.20/month in electricity. Raspberry Pi - From my point of view, the key benefit of Raspberry Pi is how little power it consumes.If you have ever seen the flightradar24 website before, you have possibly thought (I know I did) about how cool would it be to do it yourself - own one of those virtual radars and maybe even feed the data into flightradar24 to improve their coverage (and get premium account for free)? If you like this idea, you will like the results your own radar station will produce - in general it would be something like thisĪll of that is easy to build and the cost is really minimal, using either a PC or a Raspberry Pi as I describe in this post.

The full Wikipedia article is quite interesting and contains more information. All of this happens over radio broadcasts (completely public) at 1090MHz - at lest this is the frequency we are interested in. This is one of the ways in which the airplanes report their basic flight parameters (identification, current position, altitude, speed, etc) to the Air Traffic Control.
There are purpose built systems that are quite expensive so why not to do it on a budget and have some fun with it?ĪDS-B Basics Automatic dependent surveillance-broadcast (ADS-B) is a cooperative surveillance technology for tracking aircraft. One of the ideas I had for a long time was to build a virtual radar type system that would allow me to see airplanes that fly over my area. Mine spent most of that year in the drawer, so I decided to see if I can use it as low power server for a particular task. As you probably know it's been over a year since Raspberry Pi hit the market.
