Question: What is the primary purpose of the UAS Identifier (UAS ID) in the context of Uncrewed Aerial Systems (UAS)?
Option 1: To uniquely identify a pair of UAV and UAV-C collectively known as UAS.
Option 2: To authenticate communication between the UAS and cellular networks.
Option 3: To provide location services for emergency response situations.
Option 4: To manage data transmission rates for UAS-related communications.
Explanation: The correct answer is Option 1 because the UAS ID is specifically designed to uniquely identify a collective unit of a UAV (Unmanned Aerial Vehicle) and its control station (UAV-C), which together form a UAS. This unique identification is crucial for various operational, regulatory, and safety purposes within the telecommunications and aviation sectors.
