| Abstract: | According to the new triple-frequency observations of BDS-3,characteristics of the triple-frequency linear combination observations of BDS-3 are firstly analyzed,and then the high-quality combined observations are selected,finally geometry-free(GF)model and geometry-ionospheric-free(GIF)model are adopted to perform single-epoch triple-frequency carrier ambiguity resolution(TCAR)on the BDS-3 data.Experimental results show that ambiguity errors of GF model is within 0.5 cycles for the short baseline,and the ambiguity resolution success rates are higher than 88.43%.For the medium-long baseline,the ambiguity resolution success rate of GF model reduces significantly,as wide lane drops to 73.47%and narrow lane to 25.44%.Comparing with GF model,GIF model has a better ambiguity fixing ability when solving for the medium-long baseline.The ambiguity resolution success rate of wide lane is above 85.31%,which is 13%higher than that of the GF model,and narrow lane above 43.58%,which is 51%higher than that of GF model. |
