Abstract：By taking the smallest standard deviation of cycleslip as the standard，the wavelength of phase combination and amplification factor of ionospheric delay as the constraint condition，a linear independent carrier phase combinations for Beidou are selected.Combining with the theory of multifrequency cycleslip detection，and according to the feature of three kinds of satellites within Beidou Navigation Satellite System(BDS)，the performance of cycleslip detection in the case of different types of satellites is discussed.By using Beidou triplefrequency observation data，the performance of cycleslip correction is verified.The result shows that proposed method can detect and repair cycleslips of triplefrequency undifferenced observations of GEO and IGSO satellite.And cycleslips of observations of MEO satellite can be detected and repaired in case of high data rate.
