| Abstract: | The tropospheric refraction in the position of a GPS receiver is computed with fitting the tropospheric refraction of CORS, but the accuracy which is estimated with the available tropospheric model is low. The tropospheric refraction is gained by fitting its grids in CORS, so the accuracy can be improved. Taking the data of WUHN as an example, it is shown that the accuracy of U is better than that with estimating by tropospheric model, and is similar with the results of parameter estimation.This way is easy for the tropospheric refraction because it has been provided before computing the results of the GPS receiver. |
