What is the difference between “data” and “products?” How do I get them ?
By “data” we mean raw GPS/GLONASS pseudorange and phase observations, broadcast ephemerides, and supporting types of raw data (such as meteorological) as they are gathered by the permanent tracking sites. We use the term “products” for things like the precise estimated site coordinates, tropospheric zenith path delays and the coordinate time series. The products are generated through analysis of the raw site data. Both raw data and EPN products are available from the EPN Data Centres and/or the Central Bureau.
