Background

EPN positions and zenith tropospheric delays resulting from the routine data analysis are affected by reference frame changes and upgrades of modelling and software packages. Consequently, consistent results over time can only be generated by a reprocessing of the EPN using one unique data analysis strategy. This reprocessing is coordinated by the Chair of the EPN Reprocessing Working Group and is repeated at regular intervals.

EPN-repro1 was released in 2012
Data included: Full EPN network
Period: EPN Jan. 1996 - Dec. 2009 (GPS week 834 - 1408)
