ASD-STAN/D 1/S 4 - UAS Unmanned Air Systems

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 document does not define technological measures to protect the
confidentiality and integrity of the data broadcasted.
