Abstract

The GFZ German Research Centre for Geosciences is providing Rapid multi-GNSS orbit-, clock- and EOP-product series (EOP = Earth Orientation Parameters).

he 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 daily RINEX observation data of the International GNSS Service (IGS).

The orbit/clock product is provided:
- in the SP3-d data format,
- daily with a nominal latency of 1 day after the last observation,
- the orbit positions epoch interval is of 5 minutes.
- the satellite clock corrections epoch interval is of 30 seconds.

The EOP product is provided:
- in the IGS ERP data format,
- daily with a nominal latency of 1 day after the last observation,
- with one estimated 24 hour EOP record based on real GNSS RINEX observation data,

The products are available via ftp. The time series are provided in weekly folders, beginning with 28 January 2014 (GPS Week 1777).

For recent (latest) products used for routine applications a registration via [email protected] 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/sp3d.pdf) for the description of the Orbit-/ Clock format SP3-d).
