Abstract
The paper presents a multiloop system for tracking the radionavigation parameters of navigation satellite signals in the user equipment. Comparative analysis of accuracies of traditional tracking system with discriminators and filter in the tracking loop and the proposed system without discriminators is conducted. RMS errors of estimates and the probability of signal acquisition are studied under various SNR values. The proposed scheme is shown to outperform the traditional tracking system with discriminators.
