Satellite question devil's advocate

Question: How do you reconcile being able to see satellites with a telescope yourself without NASA computer generated images and a GPS working by satellites with a flat earth.

Devil's advocate answer:
If the earth was a cube, or cylendar shape with a flat surface or a half sphere with a flat surface, orbit could occur around the earth but the sections humans explored would be flat.  As for GPS what if the claim that it is connected to satellites could be fraudulent if a black box algorithm was used that really worked on data from cell phone towers signals.  The vector for gravitational force would be in different directions than in the ball earth model to prevent water from curving on the flat part of the earth yet still allow orbit.  The universal constant G would be wrong but the magnitude of acceleration due to gravity on earth would be approximately the same as observed by ball earth supporters near the observed surface of the earth.  This incorrect understanding about how gravity works in outer space would explain why astronomers make such massive calculation errors so frequently that some claim the universe is mainly dark energy and dark matter.  This different direction of gravitational force as the satellite is above the flat surface along with air friction explains why satellites can orbit a while but eventually fall to earth again.
