Survey grade GPS and GNSS

GNSS (Global Navigation Satellite System) is the name for receivers which can track satellites from not only the GPS system, but also e.g. Glonass.

How many Glonass satellites are operational today? Count the 'operational' ones on this page. For current GPS, see here.

Survey grade GPS systems typically produce cm accurate positions. The choice of equipment depends on your budget, the desired productivity, desired precision and whether you'll need the position immediately (stake-out) or afterwards (post-processing).
