I believe that's their own system...not ours. So they're just manipulating it.

But I'll go back and read it again.

Correct.

Whoops...I’m wrong.

GNSS is the combination of ALL the global systems including our GPS. Some receivers can use them all.

The Russians claim they can spoof them all. It is quite easy to accomplish for the civilian networks since the signals have no encryption.

However, US military GPS is on multiple frequencies and encrypted. It has protections for spoofing and the Russians do not claim they hacked that side of the system.

I suppose with powerful enough jammers they could also block military GPS but spoofing is another story.

They are spoofing GPS. Not just GLONASS. It only works on the civil frequencies. They have to break the crypto codes to spoof the military signals. But messing with civil signals can cause problems for many users.
