It does. I notice to FET is ignoring the question. I am not surprised.
Well that's just silly. There are no magical floating satellites in the air above us doing "GPS". Have you seen radio towers? Well some of those are GPS towers, that is how you get your location on the flat earth.
No, I haven't seen any of these "GPS towers" across the ocean, far from land, nor across the desert in Central Australia far from any phone, TV or even microwave antennas.
And I have personally used hand-held and in-car GPS units in those locations.
I have used my hand-held GPS unit in aircraft flying over outback Australia, the Indian Ocean, over the Tasman Sea and on-board ship in the North Sea and the Pacific Ocean.
No mobile phone services or TV services in those areas, but the GPS worked perfectly!
Sure the GPS on your "smart-phone" might give up because it probably gets its maps over the internet, but
the hand-held and in-car GPS units that I use have pre-loaded maps and need no connection to any data services.
All I need are the GNSS (Global Navigation Satellite System) signals, from the GPS (USA), GLONASS (Russian) and sometimes other satellites.
So if you expect us to believe you, please supply sound evidence and not just your baseless assertion!
But of course, silly me! You said "that is how you get your location
on the flat earth" and
I do not live on "the flat earth".
I live on the Globe! You can live where you like - seems a bit like in "Wonderland":
