<p>The method of positioning a radionavigation signal receiver comprises: a prediction step to predict reception characteristics of signals emitted by radionavigation signal sources for a plurality of land positions and time values, as a function of the positions of said sources, electromagnetic waves propagation models and topographic knowledge about the environment of each said position; a receiving step in which said receiver receives radionavigation signals; a measuring step in which reception characteristics of signals received by said receiver are measured, and a processing step to process the real measured characteristics and predicted characteristics to provide information related to positioning of said receiver.</p> |
