Precise orbit determination for BDS3 experimental satellites using iGMAS and MGEX tracking networks

open access: yesJournal of Geodesy, 2018
In this contribution, the BDS3 differential code biases (DCBs) are estimated by using the iGMAS and MEGX networks and the performance of both satellite and receiver DCBs for BDS3 is evaluated with the observational data during the period of DOY 1–180, 2017.

New Constellations for Geodesy: The IGS Multi-GNSS Pilot Project (MGEX)

open access: green, 2018
Along with the gradual deployment of new GNSS constellations, the International GNSS Service (IGS) has pursued the extension of its GPS and GLONASS work into a true multi-GNSS service. Supported by numerous national agencies and individual institutions a global network of more than 200 monitoring stations has been established, which supports tracking ...

Evaluation the static precise point positioning and fixing rate with phase ambiguity resolution using different analysis centers products. [PDF]

open access: yesPLoS ONE
The performance of precise point positioning with phase ambiguity resolution (PPP-AR) strongly depends on the quality of analysis centers (ACs) products. Nowadays, many IGS/MGEX ACs provide PPP-AR products. To give a full evaluation of PPP-AR performance

Influence of Precise Products on the Day-Boundary Discontinuities in GNSS Carrier Phase Time Transfer [PDF]

open access: yesSensors, 2021
Global navigation satellite system (GNSS) precise point positioning (PPP) has been widely used for high-precision time and frequency transfer. However, the day-boundary discontinuities at the boundary epochs of adjacent days or batches are the most ...
