For anyone who wants to see the live data for themselves, go to http://www.adsbexchange.com/ http://www.adsbexchange.com/, click 'Global Radar View'. Then click 'Menu', 'Options', 'Filters', then enable the 'Interesting' filter. It's a Sunday, so there's not too much activity. However there's currently an FBI Cessna circling west of Washington D.C. [0] There's also a plane gridding east of LA. [1] It's registered to Dynamic Aviation Group out of Virginia, a company that provides aerial intelligence, surveillance, and reconnaissance (ISR), among other things.

That web UI doesn't seem to work in Chrome, but it did work in Firefox.

  That's weird, it's working for me in Chrome. What particularly wasn't working for you?

    I maybe have just been confused by the delay/lack of confirmation + the clunky UI. On the second try it worked.

This assumes that surveillance aircraft have their ADS-B transponder on. It's not required until January 2020 (https://www.faa.gov/nextgen/programs/adsb/faq/ https://www.faa.gov/nextgen/programs/adsb/faq/).

  Running without ADS-B around major airports would be unacceptable. I think drones are going to be required to have them before 2020 which makes me think that isn't quite right.

    With ATC notified, the helicopter could revert to Mode-C [0] transponder mode, using an assigned transponder code and ATC would still track them safely. TCAS [1] would also still function safely when interrogated by secondary radar. ADS-B reduces controller workload as they don't have to manually tag individual aircraft, especially in a high traffic area. ADS-B also works without secondary radar interrogation. When there is a high speed chase near an airport, sometimes the tower controller will request the helicopter remain under a certain altitude or clear of a specific area. Additionally, websites like FlightAware.com have limited direct ADS-B coverage and also display the FAA 5-minute delayed feed. I've never heard of a "criminal" in the US using an ADS-B receiver to evade police helicopters in real time.

      Flight aware just announced real-time flight tracking data (US & Canada). [1] Also, they will be adding MLAT data. (US) [1] https://flightaware.com/news/article/Realtime-Flight-Status-And-Radar-For-All-USCanada-Flights/223 https://flightaware.com/news/article/Realtime-Flight-Status-...

      I wonder if a $12 TV Tuner RTL-SDRs can listen in to secondary radar triggered TCAS responses? (I wonder how much trouble you'd get in for setting up a USDR or HackRFOne to transmit your own "secondary radar" signals to make the TCAS respond?)

wow, those are some poorly flown lines in [2]

I've observed the Dynamic Aviation aircraft flying those patterns over LA for over a year, and while at first I thought it could be related to their surveillance operations, I'm pretty sure they're actually Sterile Insect Technique flights: http://www.dynamicaviation.com/flight-solutions-and-services/sterile-insect-technique/ http://www.dynamicaviation.com/flight-solutions-and-services... There's a lot of info online about Dynamic Aviation doing Sterile Insect Technique flights over southern California, and their contracts to do so. There are other spooky defense contractors doing what may be imagery collection flights, though.

Woah I did that, zoomed all the way out, found one aircraft over the "Firth of Clyde" (west of Glasgow). -320ft/m. Then it disappeared. Data issue or did that thing just crash? Screenshot of the data: http://i.imgur.com/2zvH6qO.jpg http://i.imgur.com/2zvH6qO.jpg

  It's a data issue.

Do you know why there is not a single military aircraft for Asia on the map? Also, for the tag "interesting", I see only one (UK something).. Is it because I'm in Europe? (Just curious)

Hmmm, on Monday morning, under the "Interesting" listing, one of the planes flying: SAN BERNARDINO COUNTY SHERIFFS DEPARTMENT - SAN BERNARDINO, CA No location coordinates provided though. I wonder if this is anything related to an ongoing investigation, or just a coincidence?
