The rapid development of the European Galileo system brings a great opportunity for real-time retrieval atmospheric parameters. In this contribution, observations are employed to retrieve water vapor based on precise point positioning (PPP) technique, where benefit ambiguity resolution sensing is also investigated. obtained parameters, including zenith tropospheric delay (ZTD) and precipitable (PWV), validated with respect postprocessing Global Positioning System (GPS) ZTD products PWV...
BeiDou navigation satellite system with global coverage (BDS-3) has been fully operational since July 2020, currently providing the positioning, and timing service together regional BDS-2. In addition to legacy signals of B1I B3I, BDS-3 also transmits several new such as BIC, B2a B2b, which brings opportunities for rapid ambiguity resolution (AR) BDS precise point positioning (PPP). this contribution, a multi-frequency (MF) PPP-AR method network augmentation was proposed. Firstly,...
<p>PPP-RTK which combines the advantages of real-time kinematic (RTK) and precise point positioning (PPP), is able to provide centimeter-level accuracy with rapid integer ambiguity resolution. In recent years, development BDS Galileo as well modernization GPS GLONASS, more than 130 GNSS satellites are available new-generation capable transmitting signals at three or frequencies. Multi-GNSS multi-frequency observations bring possibilities for enhancing performance PPP-RTK. this...
