Method for correcting prediction errors of signal values with time variation subjected to interference by various uncontrollable systematic effects

摘要

592934 Disclosed is a method for correcting prediction of values of signals with time variation. The method is implemented by a receiver of radio navigation satellite signals and includes the correction of the predictions of a parameter included in a received signal and varying time. History is constructed of a prediction error based on a first batch of values estimated during a determined time period. The first batch of values is called restored values and is compared to a batch of values previously predicted for the same determined time period. A predicted time-oriented series of prediction errors is analysed by a method for processing the signal with the contributions of the systematic effects being isolated. Extrapolation is applied to at least one prediction time period of the behavior of the contributions of the systematic effects identified during the determined time period concerned. At least one prediction is then corrected using the extrapolation of the systematic effects.
