What is the primary system used by the majority of SUAS for tracking and locating coordinates?

The primary system used by the majority of Small Unmanned Aircraft Systems (SUAS) for tracking and locating coordinates is the navigation system. This system is crucial as it usually incorporates Global Navigation Satellite Systems (GNSS), such as GPS, which provide precise location data, enabling the SUAS to determine its position accurately in real-time. This functionality is essential for various applications, including mapping, surveying, and other missions that require accurate coordinate tracking.

The navigation system works by receiving signals from multiple satellites and calculating the aircraft's position based on the time it takes for these signals to reach the SUAS. This information allows the SUAS to navigate autonomously or provide the operator with vital location data.

While other systems, such as the communication system, control system, and sensor system, are important for different functionalities of the SUAS, they do not primarily focus on the task of tracking and locating coordinates. The communication system deals with the transmission of data between the SUAS and the ground control, the control system manages flight controls and stability, and the sensor system gathers environmental data which may complement navigation but is not the main system for tracking location.
