The information presented in this AIR is intended to provide information about current remote identification methods and practical considerations for remotely identifying UAS. Depending on rigor and adherence requirements, Aerospace Standard (AS) and Aerospace Recommended Practice (ARP) documents may be developed. For example, ARPs may provide methods to remotely identify UAS using existing hardware technologies typically available to most consumers. ARPs may also specify the information exchange and message format between unmanned aerial systems and remote interrogation instruments. An AS, however, may highlight the wireless frequency band, message type, message encoding bits, and message contents.
This SAE Aerospace Information Report (AIR) discusses practical considerations for remotely identifying lightweight unmanned aerial systems (UAS), less than 55 lbs. Identification standards shall address all phases of unmanned systems operations (e.g. vehicle in flight and vehicle powered-off on the ground). There are multiple ways to achieve positive identification—passively, actively, visually, and electromagnetically. This AIR introduces multiple UAS identification methods and reviews existing identification standards and technologies.
