Abstract：On the bisis of the three carrier ambiguity resolution（TCAR）algorithm，the two improved methods，ionospheric delay correction method and the method of geometryfree and ionospherefree combination，were compared and analyzed with the Beidou/Compass triplefrequency surveying data.The experiment results show that both methods can improve the accuracy of longbaseline ambiguity resolution，and a rapid longbaseline ambiguity resolution after data smoothing with some epochs can be realized.The two methods can be useful for achieving the longbaseline precise rapid navigation and position with Beidou/Compass triplefrequency.
