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.

TL;DR: The development and numerical values of the new absolute phase-center correction model for GPS receiver and satellite antennas, as adopted by the International GNSS (global navigation satellite systems) Service, are presented and the benefits from switching from relative to absolute antenna phase- center corrections are demonstrated.

TL;DR: An initial characterization and performance assessment of the COMPASS/BeiDou-2 regional navigation system is presented and the benefit of triple-frequency measurements and extra-wide-lane ambiguity resolution is illustrated for relative positioning on a short baseline.

TL;DR: A consistent analysis of signal-in-space ranging errors (SISREs) is presented for all current satellite navigation systems, considering both global average values and worst-user-location statistics, based on 1 year of broadcast ephemeris messages of the Global Positioning System, GLONASS, Galileo, BeiDou and QZSS collected with a near-global receiver network.

TL;DR: The Experiment (MGEX) as mentioned in this paper is an early-familiarization system for GNSS systems to enable their incorporation into high-precision GNSS modeling and analysis, and it is based on the MGEX project.
