It's using the cell tower location. If you don't connect to the cell tower (Airplane mode), there's no location.

So you're saying that person quite explicitly saying this is GPS data is explicitly wrong about this? (i.e. you have more information than that person, and it is explicitly to the contrary?)

FWIW the Kerbs article makes no mention of GPS, only nearby cell towers

That person was clearly claiming to have 'insider' information. I'm not sure why one would expect Krebs to have been privy to the same information.

It does AGPS, pointed to where exactly I was in my house.

Or it's being reported as part of the E911 data for emergency services.

This seems like the most likely explanation to me.

It looks like this is the creepiest of all the ways "they" get your location:

There are 3 operating systems running in any phone:

* iOS / Android * The SIM card JVM * The baseband RTOS

And Qualcomm is in most phones, running their RexOS, which Has that IzAt service, which has full access to memory, GPS, etc, and uses this access to send your location data to Qualcomm / the carrier.
