GNSS Base station repositories

Here are some sites that you can look at to find GPS (GNSS) base stations for use in differential GPS processing.

1. ​OS National GPS Network - Base station data for the UK. FTP download from ​ftp://www.ordnancesurvey.co.uk/gps/rinex
2. ​OS-Net - Base station data for the UK. ​Direct link to data
3. ​Leica SmartNet - Think this data is probably the same as that available direct from OS? ​Login details
4. ​IGS - Global station network, but sparse
   • ​Station list
5. ​UNAVCO - Global, permanent and campaign stations, sparse
   • ​Station search app
6. ​EUPOS - Central/Eastern European network - regional coverage only but dense.
   • ​Station database
   • ​Station map
7. ​EUREF - European regional coverage, quite dense, requires registration (and possibly using their download client)
   • ​Real time data access
8. ​Trimble reference station list - some overlap with IGS, global but sparse again
9. ​CDDIS - Don't think they operate any stations themselves, just store data from IGS stations
