It's pretty much not worth arguing with them, as usual, about GPS. They just deny everything.
When they make incorrect claims that you point out or prove wrong they drop them and move onto other claims. Then they start from the beginning again in new threads.
Pretty much all of their issues with GPS come straight out of ignorance. Ignorance of the entire history of the space program, including recent history, ignorance of how GPS works, including the modules in cellphones and standalone devices, ignorance of the orbits the GPS (and other) satellites are in and how orbits work, ignorance in how extensive a ground and balloon based network would need to be in order to get global coverage, and how expensive a balloon based one would be in particular.

They just don't want to believe it is possible. They are happy in their ignorance and everyone around them threatens it so they try to expand their bubble of ignorance as much as possible.

Luckily we solved this with Relativity, which is why GPS works even when flying over the ocean.
Using very accurate atomic clocks the positioning satellites are able to transmit their "relative" times and your GPS receiver can pick them up. From the time taken for the signal to arrive, and the relative position data of the nearby satellites that is also sent your GPS receiver can work out where in the sky the satellites are and then from the transmission latencies work out where you are in relation to them.

Surely you didn't think there was no data being sent in the GPS transmissions.

We used our brains for a second.
