This article dedicate to opportunities of including vertical refraction in topographical surveying SET tacheometer.

On the base of facts experimental network we can see that topographical surveying mainly unstable on atmosphere stratification refraction which influence on measuring of vertical angles are negative.

That’s why summarily amendment unline of the Earth and refraction (f) in exceed will have such form: f = К + r.
