What technology permits users to determine their position, velocity, and time with high accuracy?

The Global Positioning System (GPS) enables users to accurately determine their position, velocity, and time by utilizing a network of satellites orbiting the Earth. GPS receivers work by triangulating signals from multiple satellites, typically four or more, which allows for precise calculations of location based on the time it takes for the signals to reach the receiver. This system provides unparalleled accuracy and usability across various applications, including navigation, mapping, and surveying.

Other options, while related to navigation, do not offer the same level of precision or applicability as GPS. The Internet Navigation System is not a standardized term and could refer to several different systems reliant on internet connectivity without the real-time positional accuracy that GPS provides. The Celestial Navigation System relies on celestial bodies for position determination, which is less precise and dependent on clear visibility of the night sky. Radar systems, while useful for detecting objects and measuring distances, do not specify positional data relative to the Earth with the same accuracy as GPS technology.
