Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at  www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

Introduction
Remote identification is the ability of a UAS in flight to provide identification information that can be
received by other parties. The objective of this document is to increase UAS operator accountability
by removing anonymity. While network remote identification is important for UTM and safety, direct
remote identification improves operator accountability by removing anonymity, and provides local
situational awareness including supporting potential law enforcement actions.
Some organizations have already created specific performance requirements of remote identification
functions, for example, existing documents and ongoing discussion in ASTM International, ASD-STAN
and EUROCAE (Figure 1). ISO/TC20/SC16 recognise that these models share a lot of common aspects
and concepts. Annex A shows the gap between this document and standards from other organizations.
NOTE See ASTM F3411-22 and prEN 4709-002.

The document is applicable to UAS that operate at low-altitude over diverse environments, including
but not limited to, rural, urban, networked, network degraded, and network denied environments,
regardless of airspace class.
This document does not to purport to address UAS operating with approval to use ADS-B (automatic
dependent surveillance – broadcast) or secondary surveillance radar transponders nor does it purport
to solve ID needs of UAS for all operations.

UAS traffic management (UTM) —
Part 8:
Remote identification
1 Scope
This document defines the generic concept and common framework of unmanned aircraft system (UAS)
remote identification, which is mainly used to electronically identify an in-flight unmanned aircraft
(UA). This document sets the minimum performance standards for direct remote identification.
This document does not cover requirements for modules installed in UA or requirements for network
remote identification.
This document does not cover the identity of other information technology (IT) entities, such as the
station of the remote pilot, the workstation of the fleet manager or any other connected entity.
