High accuracy measurement is mainly limited by the error from atmospheric refraction. Accord?ing to data processing parts in real time and afterwards, two correction methods are proposed respectively. And refraction error correction and residual error models are built. By experimental validation and error comparing analysis, the simple calculation process and accurate models can be got by using these two methods, and can en?hance the accuracy of data processing in real time and afterwards.
