hasSummary
  • The German Research Center for Geosciences (GFZ) is providing ultra rapid multi-GNSS orbit-, clock- and EOP-product series (EOP = Earth Orientation Parameters). The Orbit/Clock product covers the following Global Navaigation Satellite Systems (GNSS) - GAL (Galileo) / Europe - GPS (GPS) / USA - GLO (Glonass) / Russian Federation - BDS (Beidou) / PR China - QZS (QZSS) / Japan All products are estimated using the latest version of GFZ's automated EPOS-8 GNSS processing environment and using global hourly RINEX observation data of the International GNSS Service (IGS). The orbit/clock product is provided: - in the SP3-c data format, - every 3 hours with a nominal latency of 2 hours after the last observation, - with a 48 hour sliding window orbit duration (1) the first 24 hours are estimated based on real GNSS RINEX observation data, (2) the second 24 hours consist of an orbit/clock prediction, - the orbit positions epoch interval is of 15 minutes. The EOP product is provided: - in the IGS ERP data format, - every 3 hours with a nominal latency of 2 hours after last observation, - with one estimated 24 hour EOP record based on real GNSS RINEX observation data, - with one predicted 24 hour EOP record. For recent (latest) products used for routine applications a registration via mgnss@gfz-potsdam.de is needed to get special access. Products with an age older than 2 days are available without restrictions. For the used data formats see Kouba and Mierault (2010, https://igscb.jpl.nasa.gov/igscb/data/format/erp.txt) for the description of the EOP Product Series and Hilla (2010, https://igscb.jpl.nasa.gov/igscb/data/format/sp3c.txt) for the description of the Orbit-/ Clock format SP3-c). The time series are provided in weekly folders, beginning with 27 May 2015 (GPS Week 1846).
