The British Isles continuous GNSS Facility (BIGF) supports research scientists with archived RINEX format GNSS (Global Navigation Satellite System) data, metadata and derivative products. This unique Facility in the UK is hosted at the British Geological Survey. BIGF was funded by the Natural Environment Research Council (NERC) from 2002 to 2018 and has been funded by United Kingdom Research and Innovation (UKRI) since 2018.

The archive comprises RINEX data from GPS and GLONASS satellites from a high density network of around 160 continuously recording stations sited throughout mainland Britain, Northern Ireland and Ireland. The data is provided to BIGF free-of-charge by a number of collaborators. We automatically receive, quality control and archive the data, which we then process into derivative products. Galileo data will be archived as it becomes available.

After quality control and archiving, the data can be supplied, on request and free-of-charge, for approved usage. They have utility in improving relative positioning accuracy, serving as a source for mining environmental variables, and contributing to the generation of derivative products. To see how we can support your research, take a look at our services, 30s and 1Hz station networks, data sets, and the science that we enable.

To find out who can, and how to use our services, please refer to our data access information.

Acknowledging BIGF: The continued funding of BIGF depends on demonstrating its benefit to the scientific community. One way to achieve this is by acknowledging BIGF in any publication that has utilized its data or products and providing details of such publications to the facility, in accordance with our conditions of use and reuse of data and products, as well as NERC's data policy.
