What does UAS navigation primarily rely on?

UAS (Unmanned Aircraft Systems) navigation primarily relies on satellite positioning systems, such as GPS. This technology allows for precise location tracking, enabling the UAS to determine its position in relation to the Earth’s surface and navigate along a planned route. Satellite positioning is essential for various tasks, including waypoint navigation, return-to-home functions, and ensuring safe and efficient flight paths, particularly in complex environments.

Other options, while relevant in certain contexts, do not serve as the primary means of navigation for UAS. Visual cues from the operator can supplement navigation but depend heavily on the operator's line of sight and are limited by factors such as visibility and range. Paper maps and compasses are outdated for UAS operations, lacking the accuracy and real-time functionality of GPS-based systems. Local air traffic control can provide valuable guidance; however, this method does not replace the fundamental need for precise navigation provided by satellite systems.
