IERS Working Group on Site Coordinate Time Series Format, 2012-2020

Please note that this IERS component ceased operation in 2020.

The IAG services that distribute GNSS, SLR, VLBI and DORIS data and products proposes plots and/or files of coordinates time series for the stations of the tracking networks, as well as web services to display these time series. The aim of this working group is to define a common exchange format for coordinates time series for the geodetic techniques.

Formerly, this was also WG 1.1.1 "Creation of common geodetic coordinate time series" of IAG Sub-Commission 1.1 (Coordination of Space Techniques).
