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 is limited to ensure conformity of the UAS with the requirements set in Parts 2, 3, 4 and 6 of Regulation (EU) 2019/945. Therefore:

• - this document does not include the capability to protect communication against user and/or malicious modification of sensors output values involved in DRI information computation (like GNSS, barometer, magnetometer, and accelerometer.) and the DRI radio-transmitter interface;
• - this document does not include the capability to protect against user and/or malicious software and hardware modification of the geographical position, the timestamp, the height, the take-off position, the speed, or the route course of the UA/add-on;
• - this document does not include the capability to ensure DRI data integrity verification, or the capability to ensure detection that the UA/Add-on´s serial number is unique, when received by the receiver mobile device. However, to provide such capabilities, a digital signature may be added to the DRI message;
• - this document does not include the capability to ensure DRI data received by the receiver mobile device are genuine and come from a UA/add-on belonging to a registered UAS operator, or the capability to ensure detection of spoofing of the UAS operator registration number. However, to provide such capabilities, a digital signature may be added to the DRI message.

Direct remote identification display software is not in the scope of this document. However, it is assumed that compatible mobile receiver devices will support DRI data interpretation and display capability
