What feature is integral for UAS navigation?

GPS technology is integral for UAS navigation because it provides precise positioning and geolocation capabilities. The Global Positioning System (GPS) uses satellites to determine the UAS's location in three-dimensional space, which is essential for maintaining control and ensuring safe flight pathways. This positioning data allows remote pilots to navigate accurately, set waypoints for automated flight, and return to launch points effectively.

While other technologies like infrared, visual cameras, and radar detection can enhance situational awareness and contribute to specific operational needs, they do not serve as the primary means of navigation. Infrared technology is often used for night operations and thermal imaging, visual cameras provide real-time video feeds but rely on the pilot's visual acuity for navigation, and radar systems can aid in detecting obstacles but do not provide the positional accuracy that GPS technology does. Therefore, GPS remains the cornerstone for reliable and efficient navigation in UAS operations.
