Earth is said to be a sphere with a circumference of 25,000 miles, or 40,000 km, therefore it has to have a curvature of about 8 inches per mile squared. Can we observe or verify this?
We are taught about the ancient observations like a sailing boat going over the horizon and the measurements of Eratosthenes. They are all falsified by our current observations and better understanding of the optical effects of the atmosphere. But how can we really measure the curvature of Earth in the 21st century?
FECORE has established the Terrestrial Laser Targeting method, or “TLT method” for short, to measure the geopotential surface of the Earth. Geopotential means the shape that the ocean surface takes under the influence of gravity.
With the TLT method, you can accurately verify or falsify the curved surface defined by the WGS84 geoid model on large bodies of water.
This is what FECORE did to measure the curvature of the Earth.
