The adjusted optical properties for Galileo/BeiDou-2/QZS-1 satellites and initial results on BeiDou-3e and QZS-2 satellites
TL;DR: A unified SRP model of ECOM+BW for Galileo, QZS-1, and BeiDou-2 orbits based on the adjusted metadata is suggested and is effective and easy to apply to the new emerging satellites in the future.

Consistency of MGEX Orbit and Clock Products
TL;DR: The analysis centers of the Multi-GNSS Pilot Project of the International GNSS Service provide orbit and clock products for the global navigation satellite systems (GNSSs) Global Positioning System, GLONASS, Galileo, and BeiDou as well as for the Japanese regional Quasi-Zenith Satellite System (QZSS).

Switching and performance variations of on-orbit BDS satellite clocks
TL;DR: It is found that the average time of on-orbit operation for BDS satellite clocks is about 1–2 years, the performances of MEO satellite clocks perform better than the IGSO and GEO satellite clock, and the average ten-thousand frequency stability of BDS satellite Clock is worse than the GPS and Galileo but better than that of GLONASS.

Precise regional L5 positioning with IRNSS and QZSS : stand-alone and combined
TL;DR: It is shown that although single-system positioning performance is rather poor, the ZTD-fixed, single-epoch ambiguity success rates (ASRs) are close to 100% when the two regional systems are combined, thus providing mm-to-cm level precision for instantaneous ambiguity-fixed positioning.
Journal ArticleDOI
Assessing the contribution of Galileo to GPS+GLONASS PPP: Towards full operational capability
TL;DR: In this paper, the authors analyzed the contribution of the Galileo constellation to GPS+GLONASS combined multi-GNSS precise point positioning (PPP) solutions in terms of static/kinematic accuracy and convergence time.
