Space systems — Rendezvous and Proximity Operations (RPO) and On Orbit Servicing (OOS) — Programmatic principles and practices
This document establishes guiding principles and best practices at the programmatic level for all participants in the rendezvous and proximity operations (RPO) and on-orbit servicing (OOS) industry. These principles and practices establish the broadest boundaries for behaviour of participants in the RPO/OOS industry and precede more detailed standards. In principle, the document also covers both robotic and HSF missions, but requirements are derived from robotic missions. This document is applicable to a broad array of RPO/OOS industry participants from spacecraft equipment manufacturers, spacecraft operators, service providers, developers of RPO/OOS simulation, planning and safety tools, and insurers. It helps to establish responsible norms of behaviour for RPO and OOS that industry participants are supposed to achieve and to promote throughout the global industry.

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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
This document outlines the principles and practices that rendezvous and proximity operations and on-
orbit servicing (RPO/OOS) service providers are expected to follow in order to ensure safe operations
and to encourage a healthy RPO/OOS industry. International law, treaties, and agreements have been
researched for compliance and reference. If additional, more specific requirements are needed for
Human Spaceflight (HSF) these can be provided in the future.
This document is intended to be the highest-level standard for the discipline of RPO/OOS for spacecraft
systems. As such, there are several places in the document where a requirement is stated, but
alternative acceptable methods of verification of compliance exist. Examples include but are not limited
to: notification of authorities (4.2.2); certifications of design or operational procedures (5.1.1, 5.1.2,
5.1.3). Clauses 4 and 5 specify programmatic principles and operational practices respectively. Annex A
contains information related to Clause 4 (A.1) and Clause 5 (A.2). Annex B outlines notional RPO/OOS
mission phases.
Initial drafts were produced by the Consortium for Execution of Rendezvous and Servicing Operations
(CONFERS) team, an international team of 26 initial companies promoting standardization for RPO/
OOS missions to improve safety and promote development of the RPO/OOS industry. Work was
performed over a period of 18 months at six international workshops in the US and Germany. With
this issue, the draft has been handed over to ISO TC 20/SC 14 for vetting and processing with the
normal ISO standardization processes. In the further development within ISO, parallel commercial and
governmental RPO/OOS efforts have contributed to the consensus requirements herein.
CONFERS is an independent, self-sustaining forum created to advocate and promote the spacecraft
servicing industry and encourage responsible commercial RPO/OOS. CONFERS collaborates on
research, development, and publication of voluntary consensus principles, best practices, and technical
and safety standards. CONFERS also engages with national governments and international bodies on
policy and oversight of spacecraft servicing activities.
