GPS receivers have come a long way.

Here's a Garmin GPS 76 from 2002, struggling to get a fix with its large internal rolled PCB antenna, seeing 3 GPS satellites. I had to go outside and got a fix after several minutes there.

Next to it my 2021 phone, picking up 9 GPS satellites (and a bunch of Russian ones the Garmin doesn't know about), which took it mere seconds. That's presumably with a ceramic antenna hidden underneath a touchscreen display.
