A general definition of initialization is that it begins at separation of the spacecraft (SC) from the launcher. In some cases, a more exact definition will be that initialization begins in flight, upon planned change in mode or state of the SC from the launch configuration. Commissioning is completed when the SC, including its payload, is certified for initial mission operations. Prior to certification for mission operations, the SC is described as a test article in the three parts of ISO 10784. ISO 10784 does not include a requirement for contingency plans, but does include a statement of the need for contingency planning.

Since the SC is considered a test article at this phase of its operational life, ISO 17566 is used as a normative reference in constructing the initialization plan and the commissioning report. It provides SC manufacturers, SC operators and other stakeholders with a common language and form to verify and document spacecraft initialization and commissioning prior to normal SC mission operations.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 10784-1 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 14, Space systems and operations.
ISO 10784 consists of the following parts, under the general title Space systems — Early operations:
— Part 1: Spacecraft initialization and commissioning
— Part 2: Initialization plan
— Part 3: Commissioning report

Introduction
The three parts of ISO 10784 provide spacecraft (SC) manufacturers and operators with a specific form and
format for writing SC initialization plans and commissioning reports required to configure and verify the SC
to perform normal mission operations. Often, SC manufacturers and operators have defined these plans
and reports uniquely for each programme, or regional, national and corporate organizations have unique
initialization plans and commissioning reports. The three parts of ISO 10784 aim at establishing a common
language and form for SC stakeholders. The use of one form and format will simplify stakeholder understanding
of initialization and commissioning activities.

Space systems — Early operations —
Part 1:
Spacecraft initialization and commissioning
1 Scope
A general definition of initialization is that it begins at separation of the spacecraft (SC) from the launcher. In
some cases, a more exact definition will be that initialization begins in flight, upon planned change in mode or
state of the SC from the launch configuration. Commissioning is completed when the SC, including its payload,
is certified for initial mission operations. Prior to certification for mission operations, the SC is described as a
test article in the three parts of ISO 10784. ISO 10784 does not include a requirement for contingency plans,
but does include a statement of the need for contingency planning.
This part of ISO 10784 outlines general descriptive information for SC initialization and commissioning as might
be appropriate for programme management, project engineering or programme test documentation. Since the
SC is considered a test article at this phase of its operational life, ISO 17566 is used as a normative reference in
constructing the initialization plan and the commissioning report. It provides SC manufacturers, SC operators
and other stakeholders with a common language and form to verify and document spacecraft initialization and
commissioning prior to normal SC mission operations.

4 Introduction clause of an initialization plan or commissioning report
4.1 General
The introduction clause of an initialization plan or commissioning report shall provide general information about
the technical content of the initialization plan and the commissioning report. It shall include a brief description
of the initialization sequence. The overall initialization objective shall be described, and the criteria for the SC
certification shall be stated.
4.2 Overall sequence of initialization events
This subclause of the introductory clause shall summarize the overall sequence of functional and operational
sequences conducted to demonstrate the initial operational status of the spacecraft with respect to the
operational environment and shall explain how the test in question fits into this sequence. The starting mode
of the spacecraft shall be the same as the launch mode. The ending mode of the spacecraft shall be the initial
operational mode.
4.3 Overall relations o
