WebFeb 22, 2024 · The correction for geodetic refraction based on this value was calculated as of the correction of the curvature of Earth, with the mean value of Earth’s radius and average refraction radius of the circular path of light about This is the common value which numerous terrestrial surveying instruments automatically apply to zenith angle ... WebAtmospheric refraction causes a distant object to appear higher than its actual position. As a result, the object can be physically behind Earth’s curvature but is still visible because the light coming from it is refracted by the atmosphere. There are many curvature calculators and simulation tools that don’t account for refraction.
