Abstract

This article discusses the issues of acceptance by consumers of various combinations of signals from global navigation satellite systems and control of the parameters of each of the separate signals. Existing methods for controlling the partial characteristics of signals are based on correlation processing, which results in the loss of measurement information and signal averaging. To eliminate these disadvantages, a method for measuring the partial power of navigation signals with frequency and code division was developed. The initial data for the method include the results of measurements of the spectral power density of the sum of signals, as well as information on the shape of the partial spectral power densities. A mathematical model of the sum of signals with overlapping spectra was analyzed. The signal powers correlated to weighting factors at partial spectral power densities. A system of equations for weight coefficients was compiled and solved by Tikhonov’s method. The metrological characteristics of the method were practically investigated. The results of this study can be used to solve problems of monitoring the technical condition of navigation spacecraft.
