That would require thousands of engineers to ne in on the conspiracy. Not 45 random people in high places.
Hey I don't believe it but others do....
Of course lol. The earth is flat! There is nothing to stop the transmissions. Its all LOSLOL.

On a more serious note - GPS requires the use of psuedolites or at least localized transmission towers to simulate the local satellites that a receiver gets its signals from. Same with communications dishes - which are pointed towards the geo-stationary satellites.

Therefore transmission towers cannot be placed on the IceWall.
Nor as of yet has anybody seen the Icewall, so no transmission towers can be verified.

The conspiracy thing is getting old.
