What does GPS stand for?

GPS stands for Global Positioning System. This term refers to the satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth. The system consists of a network of satellites in orbit around the planet, ground stations, and GPS receivers. GPS is widely used in aviation, for mapping, vehicle navigation, and many other applications.

The other options are not correct because they either represent incorrect terminology or do not accurately describe the system. For instance, Global Position Service and Global Position Sensor do not reflect the formal name of the navigation system. Similarly, Global Pilot System suggests a focus on pilot-specific functionalities rather than the comprehensive navigational capabilities afforded by the GPS technology. Understanding that "System" is part of the official name helps clarify the full scope and function of this pioneering navigation tool.
