Research on atmospheric refraction correction in precise leveling

YI You-qing

Abstract

It is necessary to reduce the error due to atmospheric refraction that is one of the main systematic errors in precise leveling.Based on the analysis of present methods for atmospheric refraction correction,a new correction model is put forward based on the refraction angle of the line of sight.This model is as accurate as classical Kukkamaki's model but with wider applications.
