Electronic License Plates for Drones May Come Soon

Drones may soon have electronic license plates, thanks to new guidelines for a remote ID system for unmanned aircraft just recently submitted for approval. The newly proposed standard, ASTM WK65041, sets up guidelines for how drones can recognise themselves to remote observers, as well as for how to set up systems to read that data. Developed with input from civil aviation authorities such as the U.S. Federal Aviation Administration (FAA) and Transport Canada, as well as leaders in the drone industry, the would be standard was submitted to global standards organization ASTM International (originally the American Society for Testing and Materials) on 5 September and will be out for ballot on 9 September.

“We’re working with a lot of drone manufacturers on this standard—DJI, for instance,” says Philip Kenul, chairman of ASTM International’s Committee F38 on Unmanned Aircraft Systems, which helped develop the newly proposed standard. “Many other companies are working with us as well, such as Google Wing and Amazon, and will comply with the standard.” The standard’s developers envision drones regularly broadcasting ID data via WiFi or Bluetooth as part of the messages such technologies normally transmit to enable other devices to figure out and link with the broadcasting device. These ID signals are understandable from a distance of 350 to 450 meters.

“Intel has done studies showing that when Bluetooth 5 comes out, we could expect a range of up to a kilometer,” Kenul says. Apps on smartphones or other devices can then link to the Internet to look up data on the drone. The public will likely only be able to read the drone's ID number, which might be the drone's serial number, or a registration number from the FAA or other civil aviation authorities. Law enforcement can get more information about the drone from its ID data, like for example its latitude, longitude, altitude, speed, direction, and takeoff point, plus its owner and operator data, and the stated purpose of the flight.

“You can just take a phone, point it up at a drone and get its electronic ID if you see it doing something dangerous. [And you can report it] just like reporting a car’s license plate number,” Kenul says. The drone can also be defined if it is connected to the Internet — say, over a cellular link through its operator. This option can prove helpful if an observer doesn't have the remote ID app, if the drone is out of range or moving too quickly for the app to acquire its Bluetooth or WiFi signals, or if high humidity in the air is degrading the Bluetooth or WiFi signals.

New drones can come automatically equipped with these types of electronic license plates. Old drones can be retrofitted with ID chips that would plug into their USB ports and might cost $7 to $12, Kenul says. In relation to radio-controlled model aircraft, the remote pilots of these vehicles can use a smartphone app to report the ID of the aircraft and the location and time of operation to remote ID authorities. Remote ID systems are answer to the development of a UAS traffic management (UTM) system, Kenul says. “Everyone knows UTM is important for drone applications, from package delivery to medical delivery, to urban area inspections, to operations after a hurricane,” he notes. “Remote ID is the first building block for UTM.”
