摘要

This article discusses the joint functioning of satellite radio navigation systems and their augmentations in the form of pseudolite networks under radio interference of various natures and intensities. The achievable precision in determining the coordinates of the object in noisy environments using and considering the estimates of the signal power level of navigational satellites, pseudolites and interference, is an indicator of the effectiveness of such joint systems. The paper refines the model of undisturbed motion of navigation satellites in terms of determining the geocentric coordinates of pseudolites (PL). A model for determining the signal levels of navigation satellites and pseudolites at the input of user equipment (UE) of satellite radio navigation systems (SRNS) was constructed. The algorithm was refined for calculating the mean square error (MSE) to determine coordinates when sharing signals of pseudolites and navigational satellites (NS) in noisy environments. The method was developed and the energy and precision characteristics of SRNS UE operated by NS and PL signals in noisy environments were determined.
