The structure of the multisignal PLL for GNSS receivers on the basis of one-stage algorithm is given. Possibility of essential simplification of calculation of coefficients of the extended filter of Kalman on the basis of communication of the decided task with simpler - the «conjugate» task is shown. Its introduction, allowed to transfer to Rikkati's equation for a vector where communication (a structure essence) errors of estimation of phases of signals from a matrix of direction cosines is obvious. Besides, such approach will allow to reduce dimensionality of correlation matrix of errors of filtering that can significantly affect time of obtaining the decision for a large number of at the same time accepted signals. Skeleton diagrams of the synthesized algorithms are received.
