IGS-MGEX: Preparing the Ground for Multi-Constellation GNSS Science [PDF]
With a total of four new and emerging constellations (BeiDou, Galileo, QZSS, IRN SS) as well as the ongoing modernization of GPS and GLONASS the world of satellite navigation presently experiences dramatic changes. Facing these challenges, the International GNSS Service (IGS) has initiated the Multi-GNSS Experiment (MGEX) to enable an early ...

PWV Retrieval Performance Evaluation for the Fresh BDS‐3 With Multisource Data
Abstract The entire global operation of the newly launched BDS global navigation satellite system (BDS‐3) was completed in July 2020. After that, a series of performance tests were conducted, such as positioning, navigation, and signal experiments. However, the precipitable water vapor (PWV) retrieval performance evaluation of BDS‐3 has not yet been ...

Real‐time precise orbit determination for FY‐3C and FY‐3D based on BDS and GPS onboard observation
(1) The real‐time precise orbit determination (POD) for low earth orbit (LEO) satellites based on spaceborne global positioning system (GPS) and BDS‐2 observations are executed. (2) Code multipath piece‐wise linear (PWL) error model of BDS‐2 satellites is constructed and applied to real‐time LEO POD.
