Position Time Series

Multi-Year EPN Solution based on EPN-repro 3

EPN station position time series:

Other residual position time series: Nevada Geodetic Laboratory

Official, solutions included up to 27-09-2025 (GPS wk 2385) (Read More)
The official multi-year EPN solution, generated by the EPN reference frame coordinator, is based on the following input SINEX files:
  1. the EPN-repro3 daily combined solutions up to GPS week 2237 (computed with epn_20.atx antenna calibration model)
  2. the routine daily combined solutions from GPS week 2238 till 2385 (computed with epn_20.atx antenna calibration model)
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 (IGc20): North, East, Up-components of the difference between the estimated positions expressed in IGc20 and a mean position value.
Position Time Series in ETRS89 (ETRF2020): North, East, Up-components of the difference between the estimated positions expressed in ETRF2020 and a mean position value.
