The British Isles continuous GNSS Facility (BIGF) is a unique and secure repository of archived GNSS* data, dating back as far as 1997. All data are in RINEX** files, which are quality-assured and accompanied by metadata, and also form the basis of derived products. BIGF serves all of these data, metadata and derived products to the complete user-spectrum - nationally and internationally across academia, government, and business - with impact on research and development, policy and the wider societal good. BIGF provides data for reference stations to satisfy positioning improvement needs but also acts as a regional natural environmental laboratory, as demonstrated through facilitated studies - of horizontal and vertical land motion, the ionosphere, and the troposphere - carried out at regional, continental and global scales over the multi-decadal extent of the archive. * Global Navigation Satellite Systems: GPS, Glonass (GLO), Galileo (GAL), Beidou (BDS). ** Receiver INdependent EXchange format.
