These plots allow to compare the daily data quality metrics of the daily RINEX data of the station SUR400EST respectively retrieved from the ROB-EUREF and SONEL EPOS-GNSS data nodes. The data quality metrics were computed independently at each node using G-Nut/Anubis software based in the daily RINEX data in the data repository connected to the node. For more information, please refer to the station tracking performance pages (you can access them by clicking on the plots below).
