A mobile device location accuracy (the location data esteem) by the distance measurement using the base stations of a local terrestrial radio navigation system signals depends on the accuracy of measurement of the distance from a mobile device to the base stations with the known positioning data. The author looks into the procedure of the direct determination of mobile devices location data with the filtration of the measured distances from a mobile device to the base stations with the known location by selecting the nonconditional measurements with the use of the base stations redundancy, whose signals are accessible to solve the positioning of a particular mobile device problem
