Their are flat earth arguments that GPS is ground based or balloons are used. My problem is I don't think satellites prove any thing about the shape of the earth. Any thing can fly around in the circle of the flat earth or fly around in the circle/orbit of the globe earth. To me, at this point, the argument is non sequitur.

Fuel.
If you're flying around in circles, you're using fuel and a lot of it. Where do these little machines store all this fuel?
The only fuel on satellites is the tiny amounts they use for maneuvering thrusters that maintain the satellite's orientation.
Also, why are geostationary satellites always 35,786 kilometers (22,236 mi) above the Earth's equator? If the Earth is flat and satellites are just flying machines, why can't they put one in geosynchronous orbit 10,500 mi above New York City?
Additionally, there are thousands of satellites in orbit and they are not all owned and operated by NASA or other government agencies. Many hundreds of satellites are privately owned by companies and other organizations spread all over the globe and are used for a very great variety of things that have nothing whatsoever to do with governmental power or control of the global society. As such the existence of these satellites creates yet another whole population of diverse people that have nothing to do with eachother except that they must all be in on the secret of the flat Earth and have somehow agreed without direct communication with eachother to maintain that deception.
The arguments here are anything but non-sequitor, what they are is devastation and destruction and mayhem to the idea that the Earth is flat.
