ADS-B is quite far away from GPS frequencies, so yeah.

ADS-B packets include coordinates from GPS as well as several values related to the estimated accuracy of said coordinates (which is how flightradar24 is reporting that they had good GPS signal throughout the flight).

    Which implies they were spoofed rather than jammed.

    This blog post has some details about the bad reporting around this story (claiming they used paper maps, and that they were circling for an hour) but it ultimately does agree that the "some issue with the GPS" reported by the pilot (the post includes radio recordings from the air and again from the ground after landing where the pilot says "GPS issues") must in fact be some type of GPS interference.

    Meanwhile flightradar24 says "Yes, and we’re also saying there is no evidence of spoofing. There are numerous issues that could have affected the crew’s ability to perform a GPS-based approach that aren’t related to jamming or spoofing."

    🤷
