Abstract Based on the quasi-measured values of tropospheric refraction,it is discussed that the exponential atmospheric model is reasonable, and according to the stable fea-ture of refractivity at 9 km above sea level, a simplified method to predict tropospheric range error is presented, and the accuracy of which is discussed. Besides, some new parameters for linear regression of tropospheric refraction are given, the improvement in prediction ef range error is distinct.
