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: In this article, differential code and phase biases of legacy and modernized GNSS signals are derived from pseudodrange observations of a global============multi-GNSS receiver network.

TL;DR: Empirical models are presented that describe the sub-daily variation of the clock offset and the inter-frequency clock difference that contribute to a better clock predictability at timescales of several hours and enable a consistent use of L1/L2 clock products in L 1/L5-based positioning.

TL;DR: Based on a network of six Compass-capable receivers, orbit and clock parameters of these satellites were determined, and a Compass-only precise point positioning based on the products derived from the six-receiver network provides an accuracy of several centimeters compared to the GPS-only results.
