BS ISO 10784-1 pdf download 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.
