So does this means that in recent days there wasn't GPS jamming but GPS satalites were broadcasting fake signals? In south Turkey people were appearing to be in Beirut airport.

No, the fact that all of these ships show the same false location strongly suggests that they are being spoofed from a single terrestrial source; this effect is not practical to achieve by modifying the signals transmitted by the satellites, even if the US wanted to for some reason.

There's a report on very similar jamming happening during the Syria conflict that will hopefully be enlightening as the methods and actors are presumably similar https://c4ads.org/wp-content/uploads/2022/05/AboveUsOnlyStar...

I'm having a hard time telling from the article - are the ships' GPSes actually reporting that they're at the airport? Or is the disconnect happening somewhere between GPS and AIS (eg they're intentionally transmitting bad location data- it's been common-ish in the past for ships to do this when doing something naughty (blockade running or illegal fishing) and given what's going on in the region I can see the value of keeping your location obscure for safety

On March 30 a friend of mine messaged me. He wrote me that his phone and his wife's phone were appearing to be in Beirut airport. But they were at home in Mersin, Turkey. On April 2 he wrote me that his phone was showing his location as Mersin correctly. During that period this map was showing GPS anomalies in Easternn Mediterranean Sea https://www.flightradar24.com/data/gps-jamming it looks like there is still anomalies.

I think it was due to Israel's some kind of defense measure against Iran.
