This document provides means of compliance with the “Direct Remote Identification” requirements set in Regulation (EU) 2019/945 on Unmanned Aircraft Systems. “Direct remote identification” means a system that ensures the local broadcast of information about a UA in operation. More specifically, this document addresses drone’s 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) contributes to address security threats and to support drones’ operators’ obligations with respect to citizens’ fundamental rights to privacy and protection of personal data. It can be used by law enforcement people, critical infrastructure managers, and public to get an instantaneous information on the drone flying around, providing various information such as UA serial number, UA navigation data and operational status, UAS Operator registration number and position as defined in the Delegated Regulation (EU) 2019/945. Since Regulation (EU) 2019/945 requires DRI information to be broadcasted using an “open and documented protocol”, this standard does not define technological measures to protect the confidentiality of the data broadcasted.


The prEN 4709-002 standard outlines the Direct Remote Identification (DRI) requirements for Unmanned Aircraft Systems (UAS) as mandated by Regulation (EU) 2019/945. This standard ensures that drones can be identified in real-time throughout their flight, using open and documented transmission protocols. Key provisions include broadcasting identification information like the UAS operator registration number and the unique serial number of the drone. The document details mandatory data fields, security measures to prevent tamp...
