PRODUCTS & SERVICES > DATA ANALYSIS

In order to optimize the data processing within the EUREF Permanent Network, the principle of distributed processing is used. In this approach the EPN is divided in subnetworks which are separately processed by different EPN Local Analysis Centres (LACs).
The below mentionned EPN LACs all process a subnetwork out of the EPN following the rules and guidelines set up by the International GPS Service and supplemented by the EUREF Technical Working Group. They submit weekly free-network solutions (SINEX format) to the EPN Regional Data Centre BKG (availability).

The EPN Analysis Centres Coordinator (Karolina Szafranek from the MUT/WUT consortium) is responsible for combining the EPN subnetwork solutions into the official combined EPN solution. This weekly solution is tied to the most recent realisation of the ITRS and is made available as SINEX files to the IGS.

BEK Bayerische Kommission für die Internationale Erdmessung of the Bavaria Academy of Science, Munich - Germany
The Bayerische Kommission für die Internationale Erdmessung of the Bavarian Academy of Science in Munich has been the Computing Center for the computation of the unified European Triangulation Network RETrig. It was also involved in the computation of the EUREF-89 GPS campaign. Since end of 1995, BEK has been producing weekly solutions of a EPN subnetwork.

BKG Bundesamt für Kartographie und Geodäsie - Germany
BKG has acquired the capacity to routinely process permanent IGS networks. Since early 1996 it has been processing part of the European Network on a weekly basis.

COE Centre for Orbit Determination in Europe, Astronomical Institute of the University of Bern - Switzerland
CODE is processing almost the complete European Permanent Network in order to create a reference solution which is used as a comparison for the solutions of the other EPN Local Analysis Centres.
The Center for Orbit Determination in Europe is a joint operation of the four institutions :
  • Astronomisches Institut (AIUB), Universität Bern, Switzerland
  • Bundesamt für Landestopographie (L+T), Wabern, Switzerland
  • Institut für Angewandte Geodäsie (IfAG), Frankfurt, Germany
  • Institut Geographique National (IGN), Paris, France
and is, as one of the IGS Analysis Centers, routinely performing global analysis of the IGS network.

EPN Local Analysis Centres (EPN LAC) not routinely submitting solutions LAC file Network
DEO Delft Institute for Earth-Oriented Space Research, Delft - The Netherlands (no submission since wk No 1546)
The Delft Institute for Earth-Oriented Space Research, a research group of Delft University of Technology, has started to process GPS networks on a regular basis since 1994. Currently, DEOS is processing several permanent and campaign networks in Europe and South-East Asia. A dedicated solution is incorporated in EUREF since February 2001.

Former EPN Local Analysis Centres (EPN LAC) LAC file Network
GOP GOP - Geodetic Observatory Pecny, Research Inst. of Geodesy, Topography and Cartography - Czech Republic (no submission since wk No 1774)
The GOP analysis centre processed subnetwork of EPN stations during the period of 1996-2014 (GPS weeks 0834-1773). In 2013, GOP suggested its reorientation towards a reprocessing activity of entire EPN network which is in effect since January 2014.
The GOP, however, still remains the IGS analysis center performing a global analysis of the IGS network in near real-time for generating ultra-rapid GNSS products.
