We discuss the problem of a periodical specification (monitoring) of the GPS/GLONASS wide-area differential subsystem. We propose a monitoring technique and a procedure for estimating the accuracy of the relative coordinates receiving antenna phase centers from the measurements of the subsystem. We describe a method for the optimal transformation of the initial multivariable system of equations with the purpose of optimizing the realization of computer processing procedures and increasing their stability when estimating information parameters. Algorithms for defining the parameters were constructed, and the accuracy of relative geodetic control of reference stations was estimated (by the example) of the wide area differential subsystem which is projected to be developed in Ukraine.
