Abstract: The observation of the present-day deformation of the Earth's surface with high spatial and temporal resolution makes up a major part of the Integrated Plate Boundary Observatory Chile (IPOC, www.ipoc-network.org). For this purpose, continuously recording GPS stations were installed in Northern Chile since end of 2002. Eleven of IPOC stations (PB01 – PB11) are equipped with permanent recording GPS receivers (TOPCON GB-1000). They continuously measure at sampling rates of both, 1 second and 30 second. The GPS data are archived and processed in GFZ Potsdam. Detailed information about data availability, metadata and site descriptions can be found at: https://kg3-dmz.gfz-potsdam.de/gnss/GFZPBOCGPS. More description about the Integrated Plate Boundary Observatory Chile (IPOC) can be found at the IPOC Website (http:/ipoc-network.org/observatory/gps/gps-at-ipoc). The Survey Mode GPS data in the IPOC Region was published by Moreno et al. (2017).

Abstract: 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).
