How do navigation systems work if the Earth is Flat?
This is an excellent question that gets asked a lot by proponents of the globe earth model. GPS and other means of navigation are major parts of our everyday life, so how do they work if the Earth is Flat?
Its All About Assumptions
What you assume determines in large part what you believe about reality. The fact that gps happens to work does not mean that the earth is round, gps works despite the fact that the Earth is Flat. Gps is programmed with round earth parameters, and those parameters work on the Flat Earth. Before I explain further, here is a quick and simple description of how the spherists think Gps works:
GPS satellites circle the Earth twice a day in a precise orbit. Each satellite transmits a unique signal and orbital parameters that allow GPS devices to decode and compute the precise location of the satellite. GPS receivers use this information and trilateration to calculate a user’s exact location. Essentially, the GPS receiver measures the distance to each satellite by the amount of time it takes to receive a transmitted signal. With distance measurements from a few more satellites, the receiver can determine a user’s position and display it electronically to measure your running route, map a golf course, find a way home or adventure anywhere.
However, on a Flat Earth the transmission and reception of signals would work just as well across the surface of the Flat plane. Remember, while Earth has topography and changing elevations, it is ultimately one large unobstructed plane. And while signals do not have infinite line of sight (atmospheric density ultimately obstructs them form traveling forever) transmitting any given signal from point A to point B is much easier than round earth believers realize. Also, the dome of Earth’s atmosphere serves as an effective means for bouncing a signal from one point to another, allowing the occurrence of trilateration described in the quote. Lets Use this pic as a reference point:
As the above picture shows, Earth’s atmospheric dome lets signals get sent from one point to another quite easily. There is NO need for supposed satellites orbiting above the Earth. All you need is a good transmitter and a handy receiver. Unfortunately, people will go on believing what they are told, ignorant of other more compelling explanations for the phenomenon they observe.
