Abstract: | In the framework of power-model of the structure function, the tropospheric limitations of accuracy of coordinate measurements, using phase and fringe frequency are shown. The general formulae, numerical estimates and a comparison between absolute and differential methods are given. It is shown that the tropospheric limitations are especially considerable for coordinate measurements, using fringe frequency. |
