Full title and description

ISO 14620-3:2021 — Space systems — Safety requirements — Part 3: Flight safety systems. This international standard defines minimum safety requirements for flight safety systems (FSSs), including flight termination systems (FTSs), tracking systems and telemetry data transmitting systems (TDTSs) used for the launch of orbital and suborbital unmanned space vehicles.

Abstract

This document sets out the minimum requirements for flight safety systems (FSSs), including flight termination systems (FTSs — externally controlled or on‑board automatic), tracking systems, and telemetry data transmitting systems (TDTSs) for commercial or non‑commercial launch activities of orbital or suborbital unmanned space vehicles. The intent is to minimise the risk of injury or damage to persons, property or the environment resulting from the launching of space vehicles. It is intended to be applied by any person, organisation or launch authority participating in launch activities unless more restrictive local requirements apply.

Scope

ISO 14620‑3:2021 specifies minimum requirements and considerations for the design, implementation and use of flight safety systems associated with the launching of unmanned space vehicles (orbital and suborbital). It covers flight termination systems (both externally commanded and autonomous), tracking systems and telemetry data transmitting systems, and is intended to reduce risks to people, property and the environment arising from launch activities. The standard is applicable to commercial and non‑commercial launch operations and may be applied by countries, organisations, agencies, operators or launch authorities, except where more restrictive national or local requirements are imposed.

Key topics and requirements

• Definition and classification of flight safety system (FSS) elements: flight termination systems (FTS), tracking systems and telemetry data transmitting systems (TDTS).
• Minimum safety objectives and intent to minimise risk to persons, property and the environment during launch.
• Applicability to orbital and suborbital, unmanned launch vehicles and both commercial and non‑commercial launch activities.
• Requirements and considerations for system independence, reliability and controls (including externally controlled and onboard automatic termination functions) — i.e., design emphasis on reducing failure modes that could increase public or environmental risk.
• Operational considerations: interfaces with launch authorities, criteria for termination, tracking and telemetry needs to support safety functions.

Typical use and users

Typical users include launch vehicle designers and integrators, flight safety and systems engineers, launch operators, launch site authorities, regulatory bodies, space agencies, and contractors responsible for flight termination, tracking and telemetry subsystems. The standard is used to inform FSS design, safety cases, verification/validation activities and regulatory compliance work.

Related standards

ISO 14620‑3 is part of the ISO 14620 series on space systems — safety requirements. Closely related parts include ISO 14620‑1 (system safety) and ISO 14620‑2 (launch site operations); older and withdrawn editions of Part 3 (2005) were superseded by the 2021 edition. Other parts of the 14620 family (and related deliverables from ISO/TC 20/SC 14) cover spacecraft assembly, integration and test and broader system safety topics.

FAQ

Q: What is this standard?

A: ISO 14620‑3:2021 is the ISO international standard that specifies minimum safety requirements for flight safety systems (including flight termination, tracking and telemetry systems) used in the launching of unmanned orbital and suborbital vehicles.

Q: What does it cover?

A: It covers the definition and minimum requirements for FSS elements (FTSs, tracking systems, TDTSs), intent to minimise risk to people/property/environment during launch, applicability to commercial and non‑commercial launches, and operational considerations such as termination criteria and interfaces with launch authorities.

Q: Who typically uses it?

A: Launch vehicle manufacturers, flight safety engineers, launch operators, launch site authorities, regulators, space agencies and subsystem suppliers use the standard to guide design, verification, operations and regulatory compliance for flight safety systems.

Q: Is it current or superseded?

A: The 2021 edition (Edition 2) is the current published edition, released in August 2021; it superseded the earlier ISO 14620‑3:2005. ISO records indicate the 2021 edition is the active published version. Users should check with national adoption bodies or ISO for any subsequent confirmations, systematic reviews or amendments.

Q: Is it part of a series?

A: Yes — ISO 14620 is a multipart series on space systems — safety requirements. Part 1 addresses system safety, Part 2 addresses launch site operations, Part 3 covers flight safety systems, and other parts address related topics; the series is managed under ISO/TC 20/SC 14.

Q: What are the key keywords?

A: flight safety systems; flight termination; tracking; telemetry; launch safety; launch vehicle; suborbital; orbital; unmanned; safety requirements.
