Official Reference Frame Solution (IGb14)

EPN station position time series:

Other residual position time series: IGS14, Nevada Geodetic Laboratory

solutions included up to 12-11-2022 (GPS wk 2235) (Read More)

The official multi-year EPN solution, generated by the EPN reference frame coordinator, is based on the following input SINEX files:

the EPN-repro2 daily combined solutions up to GPS week 1772 (corrected to be in accordance with the epn_14.atx antenna calibration model)
the routine daily combined solutions from GPS week 1773 till 1933 (corrected to be in accordance with the epn_14.atx antenna calibration model)
the routine daily combined solutions from GPS week 1934 till 2235

During the estimation, position outliers have been eliminated and discontinuities have been introduced.
Residual Position Time Series: North, East, Up-components of the position residuals with respect to the estimated station positions and velocities.
Position Time Series in ITRS (IGb14): North, East, Up-components of the difference between the estimated positions expressed in IGb14 and a mean position value.
Position Time Series in ETRS89 (ETRF2014): North, East, Up-components of the difference between the estimated positions expressed in ETRF2014 and a mean position value.
