This document outlines the evaluation methods for environmental tests that can be conducted on COTS (Commercial-Off-The-Shelf) spacecraft parts intended for use on LEO satellites. The radiation effects considered consist of total dosage, single event, and displacement damage. In addition, this document describes tests that are useful for satellites operating in LEO.

Overview

ISO 21980:2020 - "Space systems - Evaluation of radiation effects on Commercial‑Off‑The‑Shelf (COTS) parts for use on low‑orbit satellite" provides guidance for evaluating radiation effects on COTS electronic parts intended for Low Earth Orbit (LEO) satellites. The standard focuses on practical test methods and evaluation procedures to assess total ionizing dose (TID), single‑event effects (SEE), and displacement damage (DD) for small satellites, nano/microsatellites and CubeSats that increasingly use consumer technology.

Key topics and technical requirements

Radiation resistance design: Concepts for selecting and applying COTS parts, and integration of mitigation measures (shielding, part selection, design procedures - see Annex A).

Space radiation environment: Guidance on modelling LEO radiation environments, required environmental parameters, and prediction methods (Annex B, contour maps in Annex C).

Radiation tolerance tests: Prescribes irradiation test types and procedures:

Total dose tests (e.g., Co‑60 gamma irradiation)
Single‑event tests (heavy ions, proton beams)
Displacement damage tests (proton/particle fluence)
Alternative irradiation: focused pulsed laser (FPL) for SEE simulation

Test procedures & fields: Stepwise testing approaches for TID, SEE, DD and laser pulse methods (summarized in Clause 6 and Annexes K–L).

Supporting guidance: Informative annexes covering prediction methods, comparative model vs. measured data, device‑level radiation deterioration, and mitigation measures (Annexes D–J).

Note: The document contains informative annexes rather than prescriptive thresholds; it does not include normative external references.

Practical applications

ISO 21980:2020 is intended to help suppliers and designers validate COTS components for LEO missions where constrained budgets and rapid development favor consumer semiconductor use. Typical uses:

Verifying COTS component suitability for CubeSat, pico/nanosatellite and small satellite missions.

Designing radiation mitigation strategies (shielding thickness estimation, part derating, error detection and correction).

Planning and executing irradiation test campaigns (gamma, proton, heavy‑ion, laser pulse).

Estimating mission end‑of‑life radiation exposure using contour maps and environment models.

Related tools and references

Radiation modelling and analysis tools referenced in the document include SHIELDOSE‑2, SPENVIS, and CREME‑MC (used for TID and SEE estimation). The standard was prepared by ISO/TC 20/SC 14 (Space systems and operations).

Keywords: ISO 21980:2020, COTS parts, LEO satellites, radiation effects, TID, SEE, displacement damage, CubeSat, radiation tolerance test.
