Use the tool below to find stations and request data. The "search location" field expects a coordinate or grid reference see Help with input formats. Data is available for 45 days. See the "Useful links" box to download individual hourly files. The recommended maximum order size is approximately 144 station hours which is equivalent to 6stns @ 24hours. Orders larger than this may not complete correctly. The maximum number of stations that can be searched for is 20.

Note: satellite navigation data is no longer provided by this service. This data can come from users' own receiver data files. Alternatively, navigation data files can be downloaded from the Internet. For guidance on how to download navigation files see Broadcast ephemeris data from CDDIS. Follow the instruction on downloading the merged broadcast ephemeris file identified by "brdc".
Scientific and other users with an interest in historic GNSS data older than 45 days should visit the NERC British Isles continuous GNSS Facility (BIGF) www.bigf.ac.uk, which is operated by Nottingham Geospatial Institute (www.nottingham.ac.uk/ngi) at the University of Nottingham. BIGF archives all OS active station data, along with data from other continuous GNSS (GPS+GLONASS) stations in the UK, holding data that go back as far as 1997, for some stations.
OS Net reference station coordinate listing. This link opens up a comma delimited text file (15 KB) of ETRS89 coordinates of all OS Net stations, current and superceded. Coordinates are given as both cartesian (X, Y, Z) and geodetic (Lat, Long, Height). The OSGB36 National Grid km square reference and antenna height are also given.
The 'current' receiver and antenna types for any data supplied are included in the RINEX headers (and can be seen using any standard text editor). For more details on a particular station, including a history of any changes in the receiver and antenna types, IGS-style station log files for all OS Net stations are available via NERC BIGF.
