Integrated satellite clock and code phase bias combination in the third IGS reprocessing campaign
<div>In the third reprocessing campaign (repro3) initiated by the International GNSS Service (IGS), 11 analysis centers (ACs) reanalyzed GPS/GLONASS/Galileo observations spanning 1994–2020 for station coordinates, satellite orbits, clocks, biases and attitudes. To improve the robustness of satellite products, the IGS AC Coordinator (ACC) carried out the satellite orbit combination, and the reference satellite attitudes were computed by the Technical University of Graz (TUG). The clock/bias combination was performed by Wuhan University via the IGS “Precise Point Positioning with Ambiguity Resolution” (PPP-AR) Pilot Project using the PRIDE <i>ckcom</i> software.
This article aims at reporting the clock/bias combination results in the repro3. In particular, the consistencies for the combined GPS P1–P2/Galileo C1–C5 differential code biases (DCBs) and the GPS/Galileo uncalibrated phase delays (UPDs) among contributing ACs are all better than 0.1 ns and 0.05 cycles, respectively. As a result, the consistencies for the combined GPS/Galileo satellite clocks/biases are better than 10 ps, equating about 3 mm which is very close to the nominal precision of carrier-phase. In general, the Hadamard deviation and PPP-AR results confirm the higher robustness of the combined satellite clock/bias products over their original AC-specific counterparts. This is because the combined satellite clock/bias products harvest the merits of AC-specific contributions by identifying and excluding outlier solutions from the combination process.</div>

- Purpose
-
GA currently retains the role of the International GNSS Service (IGS) Analysis Centre Coordinator (ACC) along with Massachusetts University of Technology (MIT). As part of the role, GA facilitated and partly ran combinations of the third reprocessing campaign (Repro3) products from different IGS analysis centers. The satellite and station clock and bias combinations were generated by the IGS Precise Point Positioning with Ambiguity Resolution (PPP-AR) committee. GA then quality controlled these clock and bias products and merged them into the IGS suite of combined products. This paper is a description of the IGS Repro3 combined clocks and biases, and discusses some of the outcomes of the analysis results, including the quality of different GNSS satellite constellation clocks, as well as benefits of combining clocks and biases.
