As the Frequency Division Multiple Access technology is adopted in GLONASS,the receiver clock error can not be completely eliminated in double-differencing procedures,therefore the pseudo-range is used to aid the ambiguity resolution of the double-differential carrier phase observes. In the paper,a GLONASS double-differential carrier phase ambiguity resolution method that enables effective reduction of the influence of pseudo-range error was proposed. This method employed two processes,a single-differential ambiguity resolution process based on T-distributed statistic,and a double-differential ambiguity resolution process based on the famous LAMBDA method. Results from field test showed that the method could effectively restrain the impact of pseudo-range error on the double-differential ambiguity resolution process.
