There is also interesting behavior. If you physically disconnect the
Starlink GNSS receiver from the SoC, it still connects to the Starlink
satellites, but it takes up to 20-25 minutes. It looks like there is
some fallback mechanism, like RF sync on their own satellites.
But for normal operation, they use GNSS (GPS + Galileo) to set the
system time faster.

I can confirm that spoofing with “non-milspec” methods don’t seem to
work against the receiver in the Starlink terminal. I tried with a
HackRF and a USRP and it didn’t work, while an Android phone was
spoofed fine. I was however able to jam the receiver with very
moderate power levels and a sweep generated with a HackRF Portapack
and patch antenna.

Hi,
Starlink has a multisystem GNSS receiver with data filtering, so it
can't be fooled with the single HackRF (i tested it).
Here they describe another method with gps jammers:

I experimented with NMEA data injected directly into the Dishy
operating
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.
