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

1. ​Leica SmartNet - Download OS base station data for the UK

   • ​Station list
3. ​UNAVCO - Global, permanent and campaign stations, sparse
   • ​Station search app
4. ​EUPOS - Central/Eastern European network - regional coverage only but dense.
   • ​Station database
   • ​Station map
5. ​Trimble reference station list - some overlap with IGS, global but sparse again
