> GPS satellites don't send down a location, they only send down time

The GPS almanac data they transmit is effectively location. It's not literally location, but the P code isn't literally time either.

As I understand it, those capabilities are no longer present in newer (possibly all active?) GPS satellites.

What the satellites are sending is effectively THEIR orbit, not YOUR location, I think is the point.
