摘要：

The height profile of the refractive index is determined from the solution of the inverse problem by phase measurement of navigation satellite signals. An integral equation of the first kind with a nonlinear kernel is solved on the basis of an iterative algorithm, by which a linear Fredholm equation of the first kind is solved by statistical or Tikhonov’s regularization methods in each step. The density profile and total content of water vapor in the vertical atmosphere column are found from the water vapor contribution to the retrieved profile of the refractive index. Statistical estimates of the accuracy of determination of atmosphere parameters as a function of the measurement accuracy are obtained by numerical simulation for ensembles of meteorological data under different climate conditions. The first results of retrieval of the refractive index profile using the “Transit” satellite navigation system are presented. © 1999 Kluwer Academi/Plenum Publishers.
