Data Analysis

The EPN GPS data are routinely analysed by several analysis centres. Look at who they are and which stations they process.

Weekly EPN Solutions

The core product of the EUREF Permanent Network is the weekly coordinate estimates for the EPN tracking stations and their covariance information in the SINEX format. These coordinates are outcome from the so-called "combined EPN solution" which is based on the subnetwork solutions submitted by the EPN Analysis Centres.

Coordinates

Coordinates of the EPN stations in the different realizations of the International Reference System (ITRS) and European Terrestrial Reference System (ETRS89). The most recent set of coordinates includes all EPN stations included in the EPN from before Jan. 2000.
New results including EPN-REPRO1 available!!

Position time series

An accumulation of the weekly EPN solutions provides for each EPN station the time variability of its coordinates. These coordinate time series are obtained through 4 different methods. They are available in graphical form here.

Tropospheric delays

Within the routine analysis of a network of ground-based GPS receivers, such as the EPN, the tropospheric parameters are a by-product of the parameter estimation. The EPN makes available the tropospheric zenith path delays at all of its stations based on the estimates of all its Local Analysis Centres.
Nnew results including EPN-REPRO1 available!!

ETRS89/ITRS transformation

This tool allows to transform coordinates (position and velocity) from any ETRFxx to any ITRFyy (or ITRFyy to ETRFxx).

Satellite Orbit and Clock Correction Streams

Real-time orbit and clock corrections are estimated by the IGS and its real-time Analysis Centres in the IGS-Real Time Pilot Project. The EPN gives access to the real-time satellite orbit and clock correction streams for GPS and GLONASS satellites which are related to ETRS89.
