摘要
In precise GPS measurement, one of the largest error sources is the correction for atmospheric refraction. It has become important to study the atmospheric refraction theory, to establish a more practical model, and to derive a precise correction formula. In this paper the theory of atmospheric refraction was studied in depth, a new atmospheric model was established, and a new and more precise correction formula for refraction was derived.
