Abstract

A method for determining a model of an electron distribution in the Earth's atmosphere in order to correct time-of-flight measurements of signals that are transmitted by earth satellites for position determinations with signal receivers includes determining local electron density data of provision sites and determining a local resolution accuracy as a function of the electron density data of the provision sites. The method further includes determining functions for interpolation of a distribution of the determined electron density data of the provision sites as a function of the determined resolution accuracy and compiling the model of the electron density distribution with the determined electron density data of the provision sites and the determined functions for interpolation.
