Regional modeling of tropospheric delay considering vertically and horizontally separation of station for regional augmented PPP
TL;DR: Considering the height and horizontal separations between stations, a method to regionally model the tropospheric delay is proposed in this paper, where the ZTD is separated into vertically correlated and horizontally correlated components, which are to be regionally modeled respectively.

The benefit of Galileo E6 signals and their application in the real-time instantaneous decimeter-level precise point positioning with ambiguity resolution
TL;DR: In this article , the authors evaluated the performance of instantaneous decimeter-level PPP AR with GPS/Galileo E6 signals with real-time orbit, clock and phase biases provided by the Centre National d'Études Spatiales Navigation Team.

Characteristics and modelling of BDS satellite inter-frequency clock bias for triple-frequency PPP
TL;DR: The IFCB results from consecutive two-month BDS triple-frequency observation data of 44 globally distributed Multi-GNSS Experiment (MGEX) stations show that the IFCBs of GEO satellites have prominent periodic variation in general and the model of MEO satellites performs worse than GEO and IGSO due to the numerical instability and less obvious periodicity.

BDS/GNSS multipath reflectometry (BDS/GNSS-MR) based altimetry with new signals: Initial assessment and comparison
TL;DR: In this paper, all types of BDS-3 SNR data collected from seven International GNSS Service (IGS) stations are analyzed signal by signal in terms of SNR quality and altimetry performance, while the legacy BDS B2I and Global Positioning System (GPS) L2C signals are also selected for comparison.
