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).
