Hi,

Starlink has a multisystem GNSS receiver with data filtering, so it
= can't be fooled with the single HackR=46 (i tested it).

Here they describe another method with gps jammers:=



I experimented with NMEA data injected directly into the Dishy operating<= br /> system, so I can tell there is no way to cheat the system.
Satellites know your location a wouldn't accept a connection from the
client in an unexpected Cell. All connection slots for all clients and areas are scheduled.

Besides this, Starlink requires valid and strict GNSS and 1PPS to sync the local clock, that's vital for the TDD system.
