Field Engineers Core team's laser experiments

FECORE laser experiment

In 2018, the FECORE (Field Engineers Core) team conducted 7 high-precision laser tests across Lake Balaton in Hungary and Lake ljssel in the Netherlands to verify the water surface convexity according to the WGS84 geoid model of the globe earth.

Their tests found zero curvature in both lakes, proving the WGS84 model to be incorrect.
