Which term is a navigational system that uses satellite technology to determine location and provide directions?

• A. Global Positioning System (GPS)
• B. PIN
• C. Hardware
• D. Satellite

Answer: (A)

Global Positioning System is a navigational system that uses a constellation of satellites in orbit and ground receivers to determine exact location and provide directions. The receiver collects signals from multiple satellites, using the precise time stamps to calculate distances to each satellite. With data from at least four satellites, it solves for your latitude, longitude, and altitude, effectively pinpointing where you are and how your clock differs from GPS time. Once your position is known, GPS data can be fed into mapping software to generate routes and turn-by-turn directions. PIN is a security code, hardware refers to physical computer components, and a satellite is just the object in space—not the complete system used for locating and navigating.
