The paper focuses on the performance of multi-GNSS(GPS,BDS,GLONASS,and Galileo)precise point positioning(PPP)of three commonly used models including Un-diff
As for the problem that the non-stationary fluctuating wind induces dramatic changes of atmosphere refraction at tens of meters height above the rough ocean
Time to first fix of ambiguity is always finished by using multiple sequential epochs in real-time kinematic(RTK).Among different epochs,the residual observ
With the increasing number of global navigation satellites and redundant information,the problem of the positioning accuracy and timeliness cannot be taken
Compared with conventional RTK,Network RTK possesses the advantages of wide coverage,high real-time positioning accuracy,high reliability and etc.,which bec
A novel triple-frequency cycle slip detection and correction method for BDS is proposed to detect and correct cycle slips when the ionosphere is active.Firs
