Abstract
The influence of the Earth’s atmosphere on the results of high precision distance measurement on the baselines of up to 5 km can be taken into account due to the information on the mean integral refractive index of air along the baseline being measured, obtained with temperature, air humidity and pressure sensors. The ways on improving the accuracy of such an account, as well as the requirements to the characteristics of the respective sensors for various approximations by quadrature formulas of the mean integral refractive index are discussed.
