Question: What is the primary scope of 3GPP involvement in an Unmanned Aerial Vehicle Collision Avoidance System (UCAS) service?
Option 1: To provide real-time video feed from drones to the UTM.
Option 2: To offer a backup collision avoidance system for drones.
Option 3: To ensure timely feedback from the UTM to the MNO.
Option 4: To provide accurate live positioning information into the UTM from the UAS or MNO.
Explanation: The primary scope of 3GPP involvement in a UCAS service is to provide accurate live positioning information, which enables independent verification of the location reported by the UCAS and ensures timely feedback from the UTM to the UAS. This is crucial for ensuring safe drone operations and preventing collisions.
