Method for determining the coordinates of the board radio station in the phase radio-navigation system

Authors offer the method to determine all of the potential solutions to a determination the coordinates of the board radio station ac- cording to signals of the reference stations with usage of single operating frequency. As a criterion for the selection of the true values of the coordinates by the board radio station is used minimum of summary residual. Calculations of summary residual made without accidental error in measurement of phase shifts according to signals of the three reference stations which location is set. Obtained calculations showed that when using of this method according to signals of three reference stations we observe one minimum which corresponds to true location of the board radio station. Moreover, in the absence of error in measurement of phase shifts value of shown minimum equals zero. This allows make a choice of true solution from a set of possible coordinate values of the board radio station based on the analysis of obtained values of summary residual Q(x,y) for each of the possible solutions.
