The data is taken from aircraft [EDIT: not airlines; see traceroute66's comment], so it doesn't give full coverage of the world, but it does include other satellite navigation systems aside from just GPS. Looks like the jammed/interfered areas are: * A large part of Eastern Europe around Ukraine is missing data, and there are many jammed/interfered areas around it, including the southern coast of the Black Sea and parts of Poland and the Baltic. Part of the Baltic Sea off the coast of Kaliningrad are also jammed/interfered. * Part of Germany near Berlin, possibly part of the Ukraine-related jamming/interference? * A large part of the eastern Mediterranean and some of the Middle East around Gaza. * A small area on the India-Pakistan border near Punjab and Lahore. * Two medium-sized areas in western Myanmar. * Two small areas in New Guinea with a gap in the data between them, spanning the Indonesia-Papua New Guinea border. * Two small areas in western Australia. * A small area on the US-Mexico border. * A dot in southern China with some gaps in the data around it near the border with Vietnam. Ukraine, Gaza, and Myanmar all have major conflicts going on. Other comments have suggested that the US-Mexico interference might be related to drug cartels. The India-Pakistan border is a longstanding point of tension. Not sure what (if anything) is going on in New Guinea and Australia. The jamming/interference in India-Pakistan, US-Mexico, and China all went away in the last 6 hours -- they're only visible in the 24-hour data.

> The data is taken from airlines No. It is not. The data is ADS-B data which is broadcast by aircraft. FR24 (and other similar services) obtain the data via a community[1], you can take part too[2]. For certain parts of the world, they may have the option to augment the data via commercial services, but that is highly unlikely to be on a global basis. Conclusion: Missing coverage means no community coverage in that area and no commercial augmentation.

  Could you use weather balloons transmitting ADS-B where there are gaps?

  Probably better to support a non-commercial ADS-B tracking site.

Plus it's kinda of a money hungry commercial enterprise. Same reason that Raytheon bought FlightAware and Silversmith Capital Partners via JETNET bought ADSBexchange -DATA = CASH - the later buyout is going to court because they apparently stole IP from the company that built the infrastructure. https://www.documentcloud.org/documents/23963235-golden-hammer-v-jetnet-et-al https://www.documentcloud.org/documents/23963235-golden-hamm... - wild stuff in there!

> Part of Germany near Berlin, possibly part of the Ukraine-related jamming/interference? Of the four tiles in that area (for March 19th at least), one is entirely in Poland, one is covering the Polish-German border, one is a bit of the German coast around Rügen but mostly the Baltic Sea, and the other is Bornholm (island in the Baltic Sea) and a bit of the Swedish coast. My guess is, this is part of a larger system to limit Russian military use of the Baltic, and possibly also a single layer of defence against Russian aircraft and missiles targeting Berlin and Copenhagen. Likewise, I would guess that the strip of interference from St Petersburg in the direction of Moscow is a similar single-layer of defence by Russia. At this resolution, it also looks like the west is interfering with access to St Petersburg and someone (could reasonably be either side) is worried about Kaliningrad, but that image is also also making me think "WTF?" about the Gulf of Riga. The single tile near Kandalaksha (Russia) suggests something interesting is going on there, but I have no idea what that might be, and there's a non-zero possibility that it's a deliberate red-herring to make western analysts waste time — as an analogy, imagine a troll releasing three greased pigs with the numbers "1", "2", and "4" painted on the side.
