Not really news. The Iranians downed one of our drones this way. We don’t know exactly what technology they were using but it is not new.

Many years ago, before Clinton ended obfuscation, the most precise navigation bits were available only to military receivers. Before then it was common to install a special GPS transmitter at airports to supplement the satellite information. Set it up incorrectly and all local GPS would be off.

Military receivers are supposed to have an encrypted mode to protect them from spoofing, but apparently it was not enabled or was not installed in the drone. Probably the latter in order to protect the hardware from loss, or because MILSPEC miniaturized GPS chips are unavailable, or some combination thereof.
