IGS-MGEX: Preparing the Ground for Multi-Constellation GNSS Science [PDF]

open access: green, 2013
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 ...

A Novel Method to Estimate Multi-GNSS Differential Code Bias without Using Ionospheric Function Model and Global Ionosphere Map

open access: yesRemote Sensing, 2022
Global navigation satellite system (GNSS) differential code bias (DCB) is one of main errors in ionospheric modeling and applications. Accurate estimation of multiple types of GNSS DCBs is important for GNSS positioning, navigation, and timing, as well ...

Performance Assessment of Multi-GNSS PPP Ambiguity Resolution with LEO-Augmentation

open access: yesRemote Sensing, 2023
The fast motion of low Earth orbit (LEO) satellites provides rapid geometric changes in a short time, which can accelerate the initialization of precise point positioning (PPP).

PWV Retrieval Performance Evaluation for the Fresh BDS‐3 With Multisource Data

open access: yesEarth and Space Science, Volume 10, Issue 10, October 2023., 2023
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

open access: yesIET Radar, Sonar &Navigation, Volume 17, Issue 8, Page 1213-1229, August 2023., 2023
(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.
