One of the problems law enforcement has with drones is that they tend to be difficult to identify from a distance. Manned aircraft have a unique and visible tail number and typically a transponder, which allows the aircraft to be identified by air traffic control and law enforcement.
Under certain conditions civil aviation authorities grant special permissions to operators to fly in otherwise restricted airspace or to fly over crowds of people (e.g. a sports stadium). The challenge for law enforcement monitoring a restricted airspace is to identify which drones have received authorization and which have not and pose a potential security threat.
Electronic identification of drones will allow law enforcement to do that. Most countries still do not have such a system in place and do not yet require electronic identification, but this will eventually become mandatory everywhere.
- Legal noncompliance and fines.
- Destructive interception of drones.
- Determine if local legislation requires electronic identification and if so validate compliance.
