Most of these GPS-jammed zones are, obviously, near areas of active conflicts (Ukraine, Myanmar, Isreal/Palestine, Kashmir, etc). But what's going on in Western Australia? And South-west Texas?
I've been working on mapping GPS jamming using ADS-B data for a couple years, and I'll try to address questions and points brought up here based on what I know. Relevant previous posts on HN: 2022: https://news.ycombinator.com/item?id=32245346 2023: https://news.ycombinator.com/item?id=37868106 (From my comment on that 2023 post: "Why haven't FlightRadar24, FlightAware, or any of the other flight trackers done this?"…
I'm not a NATO strategist or anything, so I'm adding this as a child comment, but I think the big story in the GPS/aviation world these days is probably Russia's n̵e̵a̵r̵-̵c̵o̵n̵s̵t̵a̵n̵t̵ frequent jamming of GPS over Poland, Finland, Sweden, Estonia, and Lithuania. Degrading and even neutralizing strategic infrastructure in EU and NATO countries, significantly affecting commercial aviation at the least, is a big dea…

Does this affect everyone there? Google maps on people's phones etc?

>"There's some reluctance to say it's Russia doing the jamming, though that seems to be the consensus among experts." Why the reluctance? I do not think there is much love lost in regards to Russia.

It's kind of neat how this works: > As part of the ADS-B messages we receive from each aircraft, the Navigation integrity category (NIC) encodes the quality and consistency of navigational data received by the aircraft. The NIC value informs how certain the aircraft is of its position by providing a radius of uncertainty. > Poor NIC values alone might indicate a problem with an aircraft’s equipment or unfavorable pos…
Do aircraft systems really only use GPS and not the full constellation of navigational satellite systems? Besides GPS, the GNSS currently includes other satellite navigation systems, such as the Russian GLONASS, and may soon include others such as the European Union’s Galileo and China’s Beidou. https://www.terrisgps.com/gnss-gps-differences-explained/
Just for the record, this must have been written ages ago. Today you would rather look up to NavIC joining them as a global system and QZSS operating independently from GPS soon.
Is interference the same as jamming? I am absolutely no expert in this but I can imagine that even natural occurrences can interfere with the GPS.
- ADS-B messages include position information from Global Navigation Satellite Systems (GNSS), like GPS, Galileo, GLONASS, BeiDou, etc.
- It is not possible to directly measure GNSS interference, but we do calculate the NIC (Navigation integrity category) for ADS-B messages.
- The NIC value encodes the quality and consistency of navigational data received by the aircraft.
- Poor NIC values alone might indicate a problem with an aircraft’s equipment or unfavorable positioning. However, when observed in multiple aircraft in close proximity during the same time frame, it suggests the presence of a radio signal interfering with normal GNSS operation.

Pretty neat! I starting sending data from my ASD-B feeder as well. https://airplanes.live/get-started/
This is really cool since ASDBExchange was bought out by a private equity firm and has since stopped giving out data to cool projects. I see they are being sued for IP theft and a couple other items. Link to Lawsuit in CA is below because I was reading it tonight.

> > Turkey has had a significant internal conflict with the PKK (Kurds) > PKK the terrorist organization, yes. Kurds the ethnic group, no. The Turkish government has a decades long history of discrimination against Kurds, including banning their language, even denying their existence as a people. If Turkey had treated Kurds better, PKK may well have never existed, and almost certainly would not have had as many Kurds…
Turkish Government has had many high-ranking Kurdish officials, including multiple presidents and prime ministers. There have been more Kurds served in the Turkish Army than all the other armed organizations combined. Majority of Kurds in Turkey openly support the Turkish Government, especially against the PKK terror. Several Kurdish organizations in Iraq, Syria, and Iran support the Turkish Government, especially ag…
> The Kurdish language was banned in a large portion of Kurdistan for some time. After the 1980 Turkish coup d'état until 1991 the use of the Kurdish language was illegal in Turkey.[52]
> Before August 2002, the Turkish government placed severe restrictions on the use of Kurdish, prohibiting the language in education and broadcast media.[55][56] In March 2006, Turkey allowed private television channels to begin airing programming in Kurdish. However, the Turkish government said that they must avoid showing children's cartoons, or educational programs that teach Kurdish, and could broadcast only for 45 minutes a day or four hours a week
It is true that over the last 20 years or so, the Turkish government has relaxed many (but not all) of its anti-Kurdish laws and policies. But that doesn't erase the reality of the decades of oppression which proceeded it.
