| Abstract: | The algorithm for the removal of noises from signals and for the detection and rejection of gross errors is put forward by the aid of wavelet transforms; at the same, the authors present a wavelet based algorithm for the modeling and predicting of SA errors by applying time series analysis methods to modeling of SA error. The algorithms are tested by experimental data. |
