TL;DR: Numerical insights are provided into the role taken by the multi-GNSS integration in delivering fast and high-precision positioning solutions (sub-decimeter and centimeter levels) using PPP-RTK.

TL;DR: A general method using the ambiguity-corrected phase observations without any constraints to search for the optimal GF and IF linear combination and analytically demonstrates that the noise level of this third linear combination only depends on the three frequencies.

TL;DR: In this paper, a combined reprocessing of GPS and GLONASS observations was performed to estimate combined GPS+GLONASS satellite clocks, with first results presented in this paper.

TL;DR: It is demonstrated that instantaneous ambiguity resolution is feasible, despite the relatively poor 4-s satellite receiver-to-satellite positioning geometry over Australia, thus showing that already now centimeter-level stand-alone QZSS positioning is possible with the current 4-Satellite constellation (February–March 2018).

TL;DR: In this article, the authors make use of real Galileo observations on five frequencies with a sampling interval of 1 s to study the formal and empirical ambiguity success rates in case of full ambiguity resolution (FAR), where the multipath effects are mitigated using the measurements of another day when the constellation repeats.
