Abstract

The article provides an analysis of existing approaches to determining the significance (importance) of the telemetered parameters of on-board systems of space assets for their subsequent ranking. The necessity of applying a scientific approach to the formation of the flow of telemetric information and the selection of the most significant parameters for operational data processing of modern launch vehicles is substantiated. A model of the flow of telemetric information is proposed, based on minimizing the presentation of information and determining logical relationships between parameters and modes of operation of on-board equipment. It is proposed to use graph-circuit analysis models to describe the flow. The dynamic and correlation characteristics of the telemetered parameters are considered, such as the connection with the modes of operation of on-board equipment and variability when changing the mode of operation of on-board equipment. Quantitative characteristics are proposed — coupling and variability coefficients, as well as algorithms for their evaluation. The integral characteristic — the significance of the telemetered parameter — is defined as a multiplication of the coupling and variability indicators.      

Keywords:
