European foreword
This document (prEN 4709-003:2020) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document is currently submitted to the ASD-STAN National Domain Ballot in parallel to the CEN
Enquiry.
This document was originally reviewed by the Domain Technical Coordinator of ASD-STAN's
Autonomous flying Domain.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.

Introduction
The Commission Delegated Regulation (EU)2019/945 was published in March 2019. It applies on
unmanned aircraft intended for use in the ‘open’ category, and on third-country operators of unmanned
aircraft systems.
This document gives all Economic Operators (such as manufacturers, importers and distributors and
their trade associations as well as bodies involved in the conformity assessment procedures) a viable way
to prove compliance with the requirements laid out in the Delegated Act on unmanned aircraft.
Many organizations are involved in developing a range of general technical standards for electrical safety,
EMC, environmental and a range of other standards to be applied to specific applications. For UAS the
picture is complex but an acceptable means of compliance can be completed with existing technical
standards and the use of electrical components that are intended to be incorporated into equipment and
for which a risk assessment can be undertaken.
Based on its risk assessment, it is the manufacturer’s responsibility to determine if the risk is acceptable.
The acceptable level of a product’s risk is determined in compliance with the safety objectives defined in
the Delegated Act on unmanned aircraft.
The end user of this document assumes all responsibility for the safe application of the test methods.
All relevant safety/quality procedures should be considered. Special consideration should be made when
operating the UAS for evaluations. All local, state, federal, and country laws should be considered when
operating UAS.
No patent applies to the requirement defined in this document.

1 Scope
1.1 Applicability
This document provides means of compliance of the function “Geo-awareness” specified in Parts 2 to 4 of
the Commission Delegated Regulation (EU) 2019/945 of 12 March 2019 on unmanned aircraft intended
for use in the “open” category, and on third-country operators of unmanned aircraft systems and its
annex.
The Geo-awareness is specified in Part 2 – articles (13) and (14) for Class 1 UASs, in Part 3 – articles (15)
and (16) for Class 2 UASs and in Part 4 – articles (10) and (11) for Class 3 UASs.
This document specifies the minimum performance expected from this Geo-awareness function, without
prescribing its design and implementation as far as possible.
Compliance with this document is recommended as one means of assuring that the Function will perform
its intended sub-functions satisfactorily under all conditions normally encountered in routine
aeronautical operation.
NOTE In the rest of the document, we will use “Function” to mean the object of this specification, and
equipment to identify the entity implementing this Function in whatever form.
1.2 General description of the Geo-awareness function
Geo-awareness means a function that, based on the UAS Geographical data provided by Member States
(as specified in the Commission Implementing Regulation (EU) 2019-947-article 15), detects a potential
breach of airspace limitations and alerts the remote pilots so that they can take effective immediate and
action to prevent that breach.
The Geo-awareness function manages only the following conditions:
— Horizontal and vertical boundaries of UGZ;
— Time applicability of the UGZ;
— Optional: notification or authorization required by UGZ.
Other conditions defined in the Commission Implementing Regulation (EU) 2019-947-article 15-1 are
not expressed yet by Member States and will not be treated in this version of the document.
Optionally a function of automatic alteration of the trajectory can complete the function Geo-awareness
by preventing the UA to penetrate a restricted zone (UAS geographical zone) by engaging an adequate
manoeuvre without any pilot action. The overall function is called “Geofencing”.
The function can be realized as a set of hardware and/or software components inside the UAS, in the
remote pilot station and/or on board the UA itself, which are fed by data about the applicable UAS
geographical zones for the requested zone of operation, provided by a ground service called in our
document “UAS geographical zone data service”.
The document is structured as follows:
— Clauses 1 to 3 of this document provide information required to understand the need for the Function
characteristics and tests defined in the remaining clauses. It describes typical Function applications
and operational objectives and is the basis for the performance criteria stated in Clause 4 to Clause 5
