Indeed. Google AT&T “LIS Hybrid” for location information services hybrid. The other carriers have similar offerings.
Just using cell phone tower triangulation, ANY of the carriers’ software can regionally locate you.
From there it drops down to well under 50’ ... once you get into the good stuff.
Small point: the towers ping the connected phones as much as the phones ping the towers/network. Every phone that’s on periodically has a digital ACK/NACK of sorts with the towers.
When we drove from Seattle to our new home in KY the first time I told my friends that if need be the phone company could plot my entire course as well as when I was where I was.
And via triangulation, they were able to plot the location of my phone within a few feet. As they zoomed in, the map showed the building I was in and pinpointed me at about 20 feet from the outside wall, which was pretty much dead on.
And no gps.
