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.

Characterising the GNSS correlation function using a high gain antenna and long coherent integration—Application to signal quality monitoring
TL;DR: The goal of this work is to measure the correlation function distortion that would lead to tracking error as low as 2 cm (or even less), that is 1/15000 of a chip for the CIA code or 1/5000 for the BOC(I,I).

Short-term GNSS satellite clock stability
TL;DR: The Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) satellites are the least stable of the GNSS constellations in the short term and will need high-rate corrections to produce RO results comparable to those from the other GNSSconstellations.
