Abstract
At present, only one classical technique accounting refraction during periods of undisturbed images allows one to largely compensate the influence of refraction on the results of geodetic measurements. However, these periods are very short, and their limits are extremely difficult to estimate. Therefore, despite many years of effort, the problem of accounting for refraction in geodetic measurements has not received a satisfactory practical solution. According to the studies of the turbulent method, the accuracy of the refraction determination corresponds to the instrumental accuracy of the device used, even in conditions of unstable temperature stratification of the atmosphere, when significant fluctuations of the angle of arrival are observed.
