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 for the last 30 days.
2. ​Leica SmartNet - Think this data is probably the same as that available direct from OS?
3. ​IGS - Global station network, but sparse
   • ​Station list
4. ​UNAVCO - Global, permanent and campaign stations, sparse
   • ​Station search app
5. ​EUPOS - Central/Eastern European network - regional coverage only but dense.
   • ​Station database
   • ​Station map
6. ​EUREF - European regional coverage, quite dense, requires registration (and possibly using their download client)
   • ​Real time data access
7. ​Trimble reference station list - some overlap with IGS, global but sparse again
8. ​CDDIS - Don't think they operate any stations themselves, just store data from IGS stations
