Using Galileo and BDS-3 Quad-Frequency Signals for Long-Baseline Instantaneous Decimeter-Level Positioning

<div>Positioning results with pseudoranges and ambiguity-resolved EWL/WL observations from Galileo and BDS-3 quad-frequency observations. (a) Positioning results with quad-frequency ionosphere-float model of pseudorange observations. (b) Positioning results with quad-frequency ionosphere-float model of EWL/WL observations.</div>
