| 摘要 |
The present invention relates to a method for correcting the prediction of signal values with time variation, in particular for navigation messages sent by global satellite navigation systems, characterised in that the method comprises the following steps for correcting the predictions of a parameter included in a received signal and varying with time: estimating the prediction error from a first lot of values estimated during a predetermined period of time by comparing said values with previously predicted values for the same predetermined period of time; analysing the predicted time series of prediction errors by a signal processing method and isolating the contributions of systematic effects; extrapolating the behaviour of the contributions of the systematic effects during the time period in question, and correcting the predictions using the values thus extrapolated.
