Estimation and Validation of BDS-3 IGSO/MEO Satellites Antenna Phase Center Offsetsing stations. The variation tendency and contributing factors of PCO daily estimation sequences are analyzed. The estimated PCO values for BDS-3 IGSO and MEO satellites are carried out and compared with the official published values calibrated by satellite manufacturers on the ground.On this basis,

Long-Baseline Single-Epoch RTK Positioning Method Based on BDS-3 Penta-Frequency Ionosphere-Reduced ed on the BDS-3 penta-frequency ionospheric-reduced (IR) combinations is proposed. First, the low-noise and weak-ionospheric delay characteristics of the multi-frequency combinations of BDS-3 is analyzed. Second, the multi-frequency extra-wide-lane (EWL)/ wide-lane (WL) combinations with long-wavele

Analysis of Inter-system Bias Characteristics Between GPS/BDS and Influence on PPPfor the prediction and modeling of the inter-system basic, improving the precision and convergence speed of precise point positioning. This paper constructes GPS/BDS ionospheric-free combined PPP observation equation by considering ISB parameters. On this basis, the difference between BDS-2/GPS ISB
