　　Real BDS data were used to investigate triple-frequency ambiguity resolution(AR)performance.At first,the extra-wide-lane(EWL),wide-lane(WL)and narrow-lane(NL)ambiguities were determined with the classical TCAR method,and then analysis of the influence of the residual double-differencing(DD)ionospheric delay on the NL ambiguity resolution was given.It is concluded that the residual double-differencing(DD)ionospheric delay is the key limitation to the medium range narrow-lane(NL)ambiguity resolution in step 3 of the classical TCAR method.
