What does GNSS stand for?

GNSS stands for Global Navigation Satellite System, which encompasses a constellation of satellites providing geo-spatial positioning information to a GNSS receiver on Earth. By utilizing signals from multiple satellites, GNSS can determine precise locations, enabling navigation and various applications in fields such as transportation, emergency management, and geographic data analysis. This definition aligns with the principles of satellite communications and positioning technologies, making the term accurate in describing systems like GPS (Global Positioning System), GLONASS, Galileo, and others. Each of these systems leverages a network of satellites to deliver location data globally, making GNSS a critical component in modern navigational systems and geographic information applications.
