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.

This document provides means of compliance with Parts 1 to 6 of Commission delegated (EU) .../... of XXX on making available on the market of unmanned aircraft intended for use in the ‘open’ category and on third-country UAS operators proposed in the Opinion 01/2018.
This includes compliance with product requirements for all UAS authorized to operate in the ‘open’ category (class C0, C1, C2, C3 and C4 UAS) and the electronic identification system.
This document does not cover "Specific" or "Certified" category of UAS.
Compliance with this document assists in complying with CE marking technical requirements and covers, but is not limited to:
I.   Physical and mechanical properties;
II.   Flammability;
III.   Electrical properties;
IV.   Functional Safety.
This European Standard is only applicable for UA with energy sources based on electro-chemical technologies.
Additional hazards that occur from the characteristics of the payload are excluded and are under the responsibility of the manufacturer and operator.
