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, GLONASS and Galileo. The ultra-rapid solution series is published eight times per day with a delay of around three hours. Additional Information
Version History19 May 2021 (Version 1.1): inclusion of Galileo satellite system
Methods
Based on a network of around 100 GNSS stations of the tracking network of the International GNSS Service, the GFZ analysis center generates sub-daily 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 (GFZ0OPSULT_<YYYY><DDD><HH00>_02D_15M_ORB.SP3.gz, data format: sp3: https://files.igs.org/pub/data/format/sp3c.txt),
- Earth rotation parameters (GFZ0OPSULT_<YYYY><DDD><HH00>_02D_01D_ERP.ERP.gz, data format: erp: https://lists.igs.org/pipermail/igsmail/1998/003315.html),
- summary file containing the detailed processing results (GFZ0OPSULT_<YYYY><DDD><HH00>_01D_01D_DSC.SUM).
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).
