I have a receiver that I use to feed the ADS-B Exchange network. In return I get an API key that I use to power a collection of twitter bots that tweet whenever they detect, in realtime, aircraft circling over various metro areas:

The bots have detected police and news helicopters and fixed wing aircraft, military aircraft (https://twitter.com/SkyCirclesSF/status/1227832420918935552 https://twitter.com/SkyCirclesSF/status/1227832420918935552), blimps (https://twitter.com/SkyCirclesLA/status/1213310909302493184 https://twitter.com/SkyCirclesLA/status/1213310909302493184), autogryos (https://twitter.com/SkyCirclesLA/status/1216464781869121536 https://twitter.com/SkyCirclesLA/status/1216464781869121536), power line inspection helicopters (https://twitter.com/SkyCirclesLA/status/1210280545952776193 https://twitter.com/SkyCirclesLA/status/1210280545952776193), and helicopters filming race cars (https://twitter.com/lemonodor/status/1228100397337702400 https://twitter.com/lemonodor/status/1228100397337702400).
ADS-B Exchange is the only completely uncensored, global aircraft tracking network. And it's powered by a considerable amount of specialized open source software. Even the multilateration client (https://github.com/adsbxchange/mlat-client https://github.com/adsbxchange/mlat-client) and server (https://github.com/adsbxchange/mlat-server https://github.com/adsbxchange/mlat-server) code that can determine an aircraft's position even when it's not broadcasting its coordinates, using the time-of-arrival information from multiple receivers, is online. tar1090 (https://github.com/wiedehopf/tar1090 https://github.com/wiedehopf/tar1090) is a much more efficient replacement for the old Virtual Radar Server front-end that is currently under development, and can be tried at https://tar1090.adsbexchange.com/ https://tar1090.adsbexchange.com/

For example, here are the feeder health stats for the southwestern U.S.: http://www.adsbx.org/sync/1B/ http://www.adsbx.org/sync/1B/ And here's the map of feeder locations in that region: http://www.adsbexchange.com/coverage-1B/ http://www.adsbexchange.com/coverage-1B/
- adsbx-james 7y agoGlad you are putting that data to good use!
- not_exactly__ 7y agoI follow your account on twitter. I love these!
- Rebelgecko 7y agoI believe OpenSky also doesn't censor their data, although in some areas I've looked at their coverage isn't quite as good as ADS-B Exchange. IIRC OpenSky is also a lot more permissive if you want to use their API
- jjwiseman 7y agoI know that there's a big financial incentive to censor aircraft data, and I haven't seen an explicit statement from OpenSky on their policies, so... I'm not sure.
- adsbx-james 7y agoUnfortunately OpenSky does filter data (donors and sponsors to name a few) and is nothing more than a tax dollar black hole and front for commercially selling data while supporting the for profit Sero Systems. ADSBx offered to share data, a data swap. Opensky was not interested and told us - "go fuck yourselves".
- nilkn 7y agoWhile an unfiltered network is cool, am I the only one who thinks it’s utterly reasonable for aircraft owners to want some basic level of privacy? I always have found it strange that communities of folks who very much don’t want to be tracked themselves are also very interested in aggressively tracking others.
- zik 7y agoRunning aircraft has significant externalized costs on society so it's probably not unreasonable that people should be able to keep track of that.
- jjwiseman 7y agoUnsurprisingly, there's a difference between tracking any individual and tracking aircraft. Essentially nobody is interested in aggressively tracking aircraft owned by dentists, doctors, skydivers, or whatever. The interest is in things like tracking the movements of dictators (https://twitter.com/C4ADS/status/1156234995876413441 https://twitter.com/C4ADS/status/1156234995876413441), uncovering large scale secret aerial surveillance programs (https://news.ycombinator.com/item?id=9646065 https://news.ycombinator.com/item?id=9646065), corrupt politicians and money launderers (https://tech.occrp.org/ https://tech.occrp.org/), and exposing rendition flights (https://gijn.org/planespotting-a-guide-to-tracking-aircraft-around-the-world/ https://gijn.org/planespotting-a-guide-to-tracking-aircraft-...). Tracking aircraft simply is not the same as tracking, say, all my neighbors.
- dpe82 7y agoIf your neighbors are traveling by personal aircraft then it is very much the same thing. There are a lot of privately owned GA aircraft and many of us don't particularly like everyone snooping on us. Many in this community get awfully nervous about things like police surveillance of cars, license plate tracking, etc. The Police say they need it just for special cases like crime, but we all know the dangers of dragnet surveillance. This is also dragnet surveillance; it's the same violation of privacy if the mode of transportation is different. Many on this forum think it's fun though because the mechanism is a bit nerdy and they aren't the ones being surveilled.
- Havoc 7y agoQuite a bit of volume on those feeds given that it's specific cities. Colour me surprised
- LegendaryPatMan 7y agoWhy am I not surprised to find this here?
- LargoLasskhyfv 7y agotar1090 pleases me. Thank you for bringing that up!
