Countries renew their geodetic datums every decade or so. For example, when Switzerland updated from CH1903 to (Swiss Terrestrial Reference System), Bernese GNSS was used to process all continuously operating reference stations (CORS). The software modeled the Alpine orogeny (mountain building) at the millimeter level, ensuring that the legal boundaries between farms and cantons do not drift over time.
While GAMIT is very powerful and free, Bernese is often preferred for large institutional networks requiring robust commercial support and advanced multi-GNSS handling. RTKLIB is simpler but is not in the same class for scientific precision. bernese gnss
Because Bernese calculates atmospheric delay so precisely to correct position, the byproduct is a highly accurate measurement of water vapor in the atmosphere. Meteorological agencies now integrate Bernese-processed GNSS data into weather models to improve short-term rain predictions, a field known as GNSS Meteorology.
