| 摘 要： | 在精密ＧＰＳ测量中，大气折射改正误差是最大的误差源之一。研究大的射理论，建立更加符合实地的模型，推导精确的改正公式，已成为ＧＰＳ测量研究中最重要的课题之一。本文对大层折射理论进行了深入研究，建立了新的在气层模型，推导出新的更精确的折射改正公式。

| Abstract: | The refraction error of the atmosphere is one of the largest error sources in precise GPS measurement. Studying the theory of atmospheric refraction, establishing a model which is more conformable to reality and deriving an accurate correction formula has been one of the most important subjects in GPS research. In the paper, further study on the theory of atmospheric refraction has been made, a new atmospheric model has been established and a more accurate correction formula for atmospheric refraction has been derived. |
