GPS or Global Positioning System consists of a constellation of U.S.-based navigation satellites that orbit the earth. GPS allows you to know your location anywhere on earth.

GNSS or Global Navigation Satellite System is the term used to describe the four independent satellite constellations, including GPS (United States), GLONASS (Russia), Galileo (European Union), and BeiDou (China). Consumers commonly use the term GPS to refer to GNSS and we use GPS in all of our marketing communications.
