The paper is aimed at synthesizing and analyzing an optimal algorithm for co-tracking delays and phases of pseudolite signals of different power in local navigation systems using a theory of optimal parameter estimation for several signals received by a navigation receiver in the additive mixture of the receiver internal noise. The analysis of the synthesized tracking algorithm is based on the simulation modeling of a navigation receiver taking account of nonlinear processing in discriminators. New equations describing an optimal complex tracking system that compensate the interfering signals in the processing paths of several incoming signals have been obtained. It has been shown that the use of this system ensures a reliable reception of navigational signals of significantly different power, which is relevant for local navigation systems based on pseudolites. The obtained tracking algorithms can be used in navigation equipment of local pseudolite-based navigation systems and satellite radio navigation systems GLONASS, GPS, Galileo, etc., working with the support of local navigation systems, robust principal component analysis (RPCA), total variation (TV), discriminating internal layers from radio echo sounding data of ice sheets, conjugate gradient method.
