Abstract: The error of correction for atmospheric refraction is one of the biggest error sources in precise GPS measurement.Therefore,to study the theory of atmospheric refraction,establish the model which is more conformable to reality and derive the accurate formula for calculation corrections have become one of the most important tasks in the research of GPS measurement.
