GPS is the acronym for which system?

• A. Geographic Positioning System
• B. Global Positioning Service
• C. Global Positioning System
• D. Global Positioning Satellite

Answer: (C)

GPS stands for the Global Positioning System. It’s the official name of the satellite-based navigation network that provides location, velocity, and time information by receiving signals from at least four satellites. The term uses “Global” to reflect worldwide coverage and “System” to denote the complete network and ground components, not a single satellite or a service. The other options mix up the terminology: “Geographic Positioning System” changes the descriptor; “Global Positioning Service” uses a different word, implying a service rather than a system; and “Global Positioning Satellite” would refer to a single satellite rather than the whole network.
