Earth Orientation Parameters (EOP)

EOP series are regularly submitted to the IERS, and also are available at the IAA EOP Service page.

EPN coordinate time series

EUREF Permanent GPS Network (EPN) coordinate time series is computed from analysis of available EUREF weekly solutions. The basis of this project is using non-fiducial (free network) strategy for computation of station coordinates. This strategy has some evident advantages:

Two approaches to obtain an homogeneous coordinate time series have been tested.

First one is based on re-processing of the official EPN weekly combined solutions. This processing is made in three steps:

Computed series are available here.

Second solution is based on independent combination of individual EPN Analysis Centers' solutions. The result is available here.
