Which navigation system utilizes satellites for position determination?

The Global Positioning System (GPS) is the correct answer because it relies on a network of satellites orbiting the Earth to provide accurate positioning data. GPS works by triangulating the signals received from multiple satellites, allowing for precise determination of an aircraft's location anywhere on the globe. This system operates independently of terrestrial navigation aids, making it highly reliable and accessible in a variety of environments, including over oceans or remote areas where other navigation systems might be ineffective.

In contrast, options such as the Inertial Navigation System (INS) use internal sensors to calculate position based on motion and orientation, rather than relying on external signals. Radio Navigation Systems typically depend on radio signals transmitted from ground-based stations, and Dead Reckoning involves estimating one's current position based on a previously known position and accounting for speed, time, and heading, without the use of satellite technology.
