要約

The possibility is analyzed of using an interferometer which receives radio signals from a geostationary satellite for estimating, within an exponential troposphere model, the path-integrated gradient of the tropospheric refraction index. The factors influencing the accuracy of angle-of arrival measurements are discussed and evaluated (including receiver noise, instability of the antenna phase center, and variations of the feeder line parameters). Performance requirements to the interferometer are considered.
