Which global system is represented by the acronym GNSS?

The acronym GNSS stands for Global Navigation Satellite System. This term encompasses a variety of satellite systems that provide geo-spatial positioning with global coverage. GNSS includes well-known systems like the United States' GPS (Global Positioning System), Russia's GLONASS, the European Union's Galileo, and China's BeiDou.

These systems utilize a constellation of satellites orbiting the Earth to provide accurate timing and location information to users around the globe. This position data can be crucial for a range of applications, including navigation for vehicles, aircraft, and ships, as well as for various mapping and surveying tasks.

The other options do not accurately represent the widely accepted terminology in satellite navigation. The term “Geolocation Navigation System” does not match any recognized global navigation terminology, while “Global Network Satellite Services” and “Geographic Navigation Satellite System” do not align with the standard definition or usage of GNSS. Therefore, the term Global Navigation Satellite System is the correct representation of the acronym GNSS.
