Abstract

GFZ acts as a global analysis center of the International GNSS Service (IGS) and provides ultra-rapid (last 24h), rapid (last day), and final (last week) solutions for GPS and GLONASS. The final solution series is published in daily files with a delay of about two weeks.

Methods

Based on a network of around 230 GNSS stations of the tracking network of the International GNSS Service, the GFZ analysis center generates weekly solutions using the latest development version of the EPOS.P8 Software. The solution series contains daily files (<YYYY><DDD> refers to the year and day of year of the first epoch contained in the files):

- satellite orbits (GFZ0OPSFIN_<YYYY><DDD>0000_01D_15M_ORB.SP3.gz, data format: sp3: https://files.igs.org/pub/data/format/sp3c.txt),

- clock corrections (GFZ0OPSFIN_<YYYY><DDD>0000_01D_30S_CLK.CLK.gz, data format: clk: https://files.igs.org/pub/data/format/rinex_clock302.txt),

- station coordinates (GFZ0OPSFIN_<YYYY><DDD>0000_01D_01D_SOL.SNX.gz,data format: snx: https://www.iers.org/IERS/EN/Organization/AnalysisCoordinator/SinexFormat/sinex.html),

- Earth rotation parameters (GFZ0OPSFIN_<YYYY><DDD>0000_07D_01D_ERP.ERP.g, data format: erp https://lists.igs.org/pipermail/igsmail/1998/003315.html) are provided weekly,

- summary file (GFZ0OPSFIN_<YYYY><DDD>0000_07D_07D_DSC.SUM.gz) containing the detailed processing results is provided also on a weekly basis


The file naming follows the IGS Long Product Filename (http://acc.igs.org/repro3/Long_Product_Filenames_v1.0.pdf). All files are .gz compressed. The processing is described in detail in our Analysis Center Notes (https://files.igs.org/pub/center/analysis/gfz.acn) and follows the current geodetic conventions (https://www.iers.org/IERS/EN/Publications/TechnicalNotes/tn36.htm).
