METHOD FOR DETERMINATION OF VALUE OF PRECIPITATED WATER VAPOR IN ATMOSPHERIC CORRECTION FOR GPS SIGNALS

摘要

Method for determination of value of precipitated water vapor in atmospheric correction for GPS signals relates to geodesy, in particular to methods for determination of effect of atmosphere on accuracy of range-measuring observations for artificial satellites of Earth (ASE) and can be used for determination of accurate coordinates of points of observation in geodesy, topography, cartography and construction and at forecasting meteorological data. Method for determination of value of precipitated water vapor (IWV) that is determined at radio location in direction of zenith by aero-logical observations of pressure of water vapor e and temperature T by formula that takes into account real instantaneous changes in meteorological parameters e and T. The invention proposed makes it possible to decrease error of effect of atmosphere on range-measuring observations of artificial satellites of Earth that are used for determination of accurate coordinates of points of observation.
