TLDR
In this article, a signal-in-space range error (SISRE) of about 1.1 m is obtained for the CNAV message whereas it is 0.6 m for the legacy navigation message (LNAV).Citations

TL;DR: The status and tracking capabilities of the IGS monitoring station network are presented and the multi-GNSS products derived from this resource are discussed and the achieved performance is assessed and related to the current level of space segment and user equipment characterization.
Journal ArticleDOI
Determination of differential code biases with multi-GNSS observations
TL;DR: The results indicate that GPS and GLONASS intra-frequency biases obtained in this work show the same precision levels as those estimated by DLR (about 0.1 and 0.4 ns for the two constellations, respectively, with respect to the products of CODE).

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.

Galileo status: orbits, clocks, and positioning
TL;DR: The European Global Navigation Satellite System Galileo is close to declaration of initial services and dual-frequency single point positioning with broadcast orbits and clocks of nine Galileo satellites that have so far been declared healthy already enables an accuracy at a few meters.

Comparing the ‘Big 4’ - A User's View on GNSS Performance
TL;DR: The determination and prediction of GNSS satellite orbits and clocks from measurements of global receiver networks, which forms the basis for precise point positioning applications, are discussed and the significance of satellite metadata knowledge is highlighted.

TL;DR: In this paper, the authors focus on the generation of the combined global products at CODE, where they put emphasis not only on accuracy, but also on completeness, and study the impact of GLONASS on the CODE products, and the benefit of using them.
