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.
