This document will provide means of compliance to cover the “Direct Remote Identification” system for UA of the “open Category”. This document applies to Class 1 to Class 3 and Add-On. The “direct remote identification” means a system that ensures the local broadcast of information about a UA in operation. More specifically, this document will address drone capability to be identified during the whole duration of the flight, in real time and with no specific connectivity or ground infrastructure link, by existing mobile devices when within the broadcasting range. Such functionality, based on an open and documented transmission protocol (described in this document) and developed for security purposes and social acceptance, can be used by law enforcement people, critical infrastructure managers, and general public to get an instantaneous information on the drone flying around, providing various information such as UA identifier, UA navigation data and operational status, UAS Operator identifier and position as defined in the Delegated Regulation (EU) 2019/945.
