Popis: Classical methods for determining vertical refraction have been developing for more than 300 years, but their accuracy does not correspond to the accuracy required in solving most modern scientific and applied problems (e.g., altitude transmission). This is because they are based on the assumption that the optical properties of the atmosphere do not change during the entire period of measurements. However, the atmosphere is continuously in turbulent motion. As a result, its optical properties are constantly changing randomly, which leads to a change in refraction. However, this atmospheric property is not taken into account in classical methods for determining refraction. New dynamic (turbulence) methods for determining refraction were proposed in the late 1960s. The research carried out at the Institute of Physics and Technology of the Academy of Sciences of the Turkmen Soviet Socialist Republic in 1980s–1990s, as well as at present by OOO Geodeziya i Stroitel’stvo and the Department of Geodesy of the Moscow State University of Geodesy and Cartography in Moscow, confirms the high accuracy of these methods.
