It's not his first radio software. Almost a decade ago he wrote the rtl-sdr ADS-B software dump1090 https://github.com/antirez/dump1090 . It was much easier to set up and use than prior GNU Radio 3.6 gr-airmodes (c++/python) + Virtual Radar (java) options. It went on to be forked and improved upon and it is now the community standard.

I used to have fun tracking flights over my previous home using a little usb rtl-sdr antenna attached to a raspberry pi and leveraging the dump1090 software. I moved homes, and got too lazy to re-set things up...but that dump1090 software did the trick back then. Its been a few years, so there could be better software nowadays. dump1090 was a bit of work to do the initial software setup, but thereafter was easy. The 2 versions that i recall back in the day... https://github.com/antirez/dump1090 (original i think?) https://github.com/MalcolmRobb/dump1090 (the form?) Have fun!

Or just run antirez's dump1090 https://github.com/antirez/dump1090 with the appropriate ADS-B dongle > Ever wonder what airplane is flying overhead? Also - not all planes broadcast ADS-B. Also - theres a privacy push to mask a plane's real tail number in ADS-B broadcasts - relevant for private planes (not commercial)

I've been using a Pi for a while to track ADS-B and AIS. If you haven't purchased the hardware yet head over to https://www.nooelec.com/store/ to get the SDR dongles. And then grab the latest Dump1090 https://github.com/antirez/dump1090 As for guides. It's a pretty big community so just use the keywords from above [RTL-SDR, ADSB, DUMP1090] and you should get a lot of guides on tracking aircraft.

I use this technique often and I love the simplicity it has. If you want to see a real-world usage, there is one in https://github.com/antirez/dump1090: /* Add the specified entry to the cache of recently seen ICAO addresses. * Note that we also add a timestamp so that we can make sure that the * entry is only valid for MODES_ICAO_CACHE_TTL seconds. */ void addRecentlySeenICAOAddr(uint32_t addr) { uint32_t h = ICAOCacheHashAddress(addr); Modes.icao_cache[h*2] = addr; Modes.icao_cache[h*2+1] = (uint32_t) time(NULL); } /* Returns 1 if the specified ICAO address was seen in a DF format with * proper checksum (not xored with address) no more than * MODES_ICAO_CACHE_TTL * seconds ago. Otherwise returns 0. */ int ICAOAddressWasRecentlySeen(uint32_t addr) { uint32_t h = ICA

OCacheHashAddress(addr); uint32_t a = Modes.icao_cache[h*2]; uint32_t t = Modes.icao_cache[h*2+1]; return a && a == addr && time(NULL)-t <= MODES_ICAO_CACHE_TTL; } As you can see adding a timestamp you can give a TTL to the cached entry validity without any additional effort: in that case you don't need to purge the hash table of old entries eventually, because the cache table is fixed size and the entires will get replaced.

You can pick this stuff up with a cheap RTL-SDR - it’s the ADS-B transponder on the planes. I believe services like FlightAware use this to track planes too. https://en.m.wikipedia.org/wiki/Automatic_dependent_surveill... https://github.com/antirez/dump1090 http://www.satsignal.eu/raspberry-pi/dump1090.html https://flightaware.com/live/map

I bought a "NooElec NESDR Mini 2 USB RTL-SDR & ADS-B Receiver Set" [0] from Amazon a few months ago. It worked without any issues with both Linux and OS X. I've had a ham radio license for a little over 21 years so I've always been interested in radio but the whole SDR thing is new to me. I still really haven't done a whole lot with it but it's fun to play with. The neatest thing I did was set it up on the balcony of our 23rd floor condo on Panama City Beach (facing the Gulf of Mexico) and used dump1090 [1] to plot aircraft locations (using ADS-B) on a map. I was able to "see" planes a few hundred miles away (thanks to the height and facing out over the water) but was also able to see them at pretty much ground level. I have access to a bunch of buildings (mostly on top of big hills) across the southern portion of Indiana thanks to my

job and have been thinking about building a bunch of "ADS-B receivers" (using Raspberry Pi's or similar) and putting them out in these buildings so that I can cover a wide area. (I really only probably need about three as long as I put them in the right locations, geographically speaking.) Edit: I do need to find a good external/outside antenna designed for 1090 MHz, if anyone has any firsthand recommendations. In addition, at one of these locations there's a communications tower used by a pager company to transmit pages so I've thought about building a POCSAG receiver with one of these devices as well. Unrelated to SDR, but I'm also planning on putting together a bunch of stratum 0 NTP servers (using GPS) and deploying them at these same locations as well. They will primarily be for my own use at work (ISP) but I expect to make publicly available a few stratum 1 servers as well. [0]: http://amzn.com/B00P2UOU72 [1]: https://github.com/antirez/dump1090

rtlsdr[1] is the name of the project that lets you use your $10 USB TV tuner as a software defined radio receiver (bless those osmocom people). rtl-sdr.com[2] has some more information. dump1090[3] is the particular project for decoding ADS-B broadcasts. With £15 of equipment (USB Tuner and some TV coax hacked into an antenna) I'm looking at aircraft 200+nm away [4] (though today's weather doesn't help).
