I wonder if Starlink could be used for tracking (non-Starlink) cellphones, in countries hostile to the US (so that the telecom's cell towers are not accessible). Is there enough leaked signal in low orbit, and enough data in that signal, to identify individual devices?
AFAIK, all of the US' signals intelligence satellites are in very high orbits (geosynchronous), so this probably isn't a pre-existing capability.
