Global Navigation Satellite System

Global Navigation Satellite System (GNSS) is a generic term used to describe the US Global Positioning System (GPS) and other constellations such as the Russian Global Navigation Satellite System (GLONASS) that provide geospatial positioning across the Earth.

Over the past two decades the GNSS has proved to be a very accurate and efficient method of measuring the tectonic motion of the continents.
