Products & Data
The data and products available through SWACI are based on primary data, mostly of them provided by the partners and institutions listed in the section "Home SWACI".
Furthermore, SWACI uses GNSS measurements provided by European GNSS ground networks like those of the International GNSS Service (IGS) and EUREF whose data are made available online via the Bundesamt für Kartographie und Geodäsie (BKG). Additional GNSS measurements are provided by ASI, TrigNet and UNAVCO (with support from the National Science Foundation (NSF) and National Aeronautics and Space Administration (NASA) under NSF Cooperative Agreement No. EAR-0735156).
Space base GPS data are taken from GPS measurements on board the German Geo-Research satellite CHAMP.
We are grateful to the above mentioned institutions, commissions and services for providing such important primary data which our service is based on.
Whereas the ground based data are operational with an update rate of 5 minutes, the CHAMP and GRACE data are available depending on the science data dump.
