Current research project: BIGF

The British Isles continuous GNSS Facility (BIGF) has been in operation since 1998, and then in 2002, became a member of the NERC-funded Family of Services and Facilities.

Its role is to provide a single secure central archive for continuously recorded UK GNSS reference data, and to serve these data to approved scientists, on demand. BIGF currently handles data from around 160 stations in mainland Britain and Northern Ireland. These data are provided free of charge by a number of collaborators, including the Ordnance Survey of Great Britain.

BIGF, using the expertise at NGI, also processes the raw satellite range data into a number of products, such as atmospheric water vapour delay, ionospheric delay and vertical land movement. These products have applications in research fields such as astronomy, coastal engineering, meteorology, receiver design and space weather. Again, these data can be made available to approved scientists.
