Quality assessment of multi-GNSS orbits and clocks for real-time precise point positioning
TL;DR: A comprehensive evaluation of the availability and the quality of multi-GNSS real-time orbit and clock products is provided through the comparison to the final Center for Orbit Determination in Europe (CODE) orbits, fitting long continuous orbital arcs, as well as the assessment of clock stability using modified Allan deviation diagrams.

Multi-GNSS signal-in-space range error assessment – Methodology and results
TL;DR: The present study reviews the fundamental concepts and underlying assumptions of signal-in-space range error (SISRE) analyses and presents a harmonized framework for multi-GNSS performance monitoring based on the comparison of broadcast and precise ephemerides to contribute to a better understanding and harmonization of multi- GNSS SISRE analyses and their use as key performance indicators for the various constellations.

The mixed-receiver BeiDou inter-satellite-type bias and its impact on RTK positioning
TL;DR: Analyses of BeiDou stand-alone RTK positioning using mixed-receiver types demonstrate that ISTBs could seriously affect the integer ambiguity resolution performance and that a priori correction for these biases will dramatically improve the success rate.
