Background. The relevance of this work is due to the need to improve the accuracy of tele-measurements of rocket and space technology products in difficult interference conditions, including under the influence of various kinds of destabilizing factors (CF), the frequency spectrum lies in the spectrum of the useful signal. The aim of the work is to develop a model of the process of current (in-service) identification of dynamic means of tele-measurement (DTI) and restoration of telemetered parameters (TMP) based on the introduction of minimal structural redundancy with little a priori information regarding the statistical characteristics of the useful signal and interference. Materials and methods. The analysis of the reasons affecting the accuracy of the TUE at the place of operation of the measuring object is carried out. A detailed description is given of the two main components of the total TUE error: the identification error caused by the difference between the real TUE operator and its nominal value due to the effect on the parameters of the real operator of a set of uncertain DFS, and the error in restoring the TUE input signal for the dynamic measurement mode. A model of the process of the current identification of dynamic SRT and recovery of TMP is proposed based on the introduction of an additional measuring channel and a quasi-optimal regularizing operator, which is part of the reverse filter of the recovery operator. Results and conclusions. The research results can be used to improve the accuracy of measuring systems in the dynamic measurement mode, including under conditions of exposure to RF, the frequency spectrum lies in the spectrum of the useful signal, as well as for metrological self-monitoring in intelligent measuring systems.
