It is proved in the article, that accuracy of the modern automated methods of definition of an anomalous vertical refraction to the devices equipped with CCD - sensor, makes: 1. by the videotheodolite TM3000V - 0,67”; 2. by the level SDL-30 - 0,31mm at length at distance about 100m. The offers concerning increase of accuracy of definition of a refraction are made.
