You have let to prove a link between watching TV and the earth being round. You keep just stating your premise (this ridiculous orbiting satellite theory) as a fact. I have demonstrated, over and again, that satellites orbiting the earth are not needed for TV.

As for how the manufacturers of navigation technology make the stuff, there are numerous ways to transmit a signal both wireless and with wires that do not require orbiting satellites in space.

I am sorry, you have not demonstrated “over again” that satellites are not required for TV.
My ship is currently 200 miles from the nearest land, but i can interact with this debate. We dont have cable, we dont have a terrestrial signal (in fact we dont have a terrestrial tv antenna) and i dont have a cell signal.
What i DO have is a satellite dish pointed at the sky to a satellite.
You came up with the idea of “hypothetical aircraft” which is akin to your magic pixels and dragons. You have NOT demonstrated how I can have communications or TV.
We also have 3 methods of finding our position.
1, Celestial navigation, i.e. taking fixes from the sun and stars. Requires the taking and calculation of the ships position, so cannot be done automatically.
2, Visual and radar observation of fixed objects such as land or other solid objects ( we are 200 miles from land, so we cannot use that)
3, GPS using Satellites.
We are using 1 and 3 to find our position.
We have no other antennas or receivers for receiving these magic signals you claim that Could be telling me where i am. There are no land based systems in operation such as Loran (switched off) decca (switched off) Omega( long ago switched off) and in any case all of those need dedicated receivers, multiple corrections and user input. I would know if we were using any of those systems.
We DO HAVE GPS, which uses satellites.
So other than magic pixels or dragons, it would be nice to know how we know where we are? Claiming there are ways to transmit signals does not really explain HOW we know...
And if you cannot explain, even the basics, then you have no real reason to claim that there are ways. Again magic pixels and dragons?
