Описание (английский):

This document provides requirements that are either unique or particularly relevant to large constellations of spacecraft operating in the LEO protected region throughout their life cycle, including planning, designing, testing, operating and disposal activities. The requirements in this document are applicable to large constellation owners. While some are directly applicable to the constellation owners, others are allocated to the manufactures or operators under the responsibility of the constellation owners.

Overview

ISO/TS 6434:2024 - Space systems: Design, testing and operation of a large constellation of spacecraft is a Technical Specification addressing lifecycle requirements for large constellations (defined as systems of a hundred or more spacecraft) operating in the LEO protected region. It provides guidance and mandatory requirements for planning, mission design, spacecraft design, qualification and testing, operations (including collision avoidance and RFI control), and end-of-life disposal to promote safety and long‑term sustainability of space activities.

Key topics and technical requirements

Mission design and orbit selection

Choose orbits and radial separations to minimize collision risk with other space objects and neighbouring constellations.
Configure constellations to limit intra-constellation collision probability and to tolerate contingencies.

Space debris mitigation

Constellations must meet ISO 24113 debris-mitigation requirements (or stricter rules where specified).
Perform aggregate assessments of long‑term debris evolution and risks (e.g., impact on other operators, Kessler-syndrome likelihood).

Spacecraft reliability and design

Prevent DoA (dead-on-arrival), accidental break-ups, and unintended loss of control.
Components with limited operational/storage life must be tracked; critical disposal hardware must be demonstrated on-orbit or rigorously tested.
Post-mission orbital lifetime generally must not exceed the spacecraft’s designed operational life (maximum five years).

Qualification and testing

Verification and validation consistent with established procedures; comprehensive pre-launch test/checkout for mass-produced units.

Operations and collision avoidance

Ongoing quality/reliability control, conjunction assessment procedures, and operational RFI/visual brightness mitigation.

Disposal and passivation

Defined criteria for initiating disposal, decommissioning actions, spacecraft passivation, and consideration of active debris removal where applicable.

Practical applications and users

Primary users: large constellation owners (responsible for compliance), system integrators, manufacturers, and operators.

Other stakeholders: launch service providers, national regulators and licensing bodies, space situational awareness (SSA) organizations, and orbital debris researchers.

Practical benefits: supports licensing and approval, reduces collision and re‑entry hazards, improves supplier selection (launch and hardware), informs operational procedures for conjunction management, and helps demonstrate commitment to the long‑term sustainability of LEO.
