Описание (английский):

This document describes internal and external interfaces of CubeSat. The internal interface includes the interface between components and the interface between a CubeSat platform and a mission payload. The external interface is limited to the umbilical connectors, i.e. access port. The document also describes the items to be included in the datasheet of the CubeSat components and platforms. The datasheet requirements apply to catalogued commercial products ready for sale. This document does not cover the interface between CubeSat and its deployer, i.e. POD. This document is applicable to CubeSats of all sizes.

Overview

ISO 17981:2024 - Space systems - Cube satellite (CubeSat) interface - defines standardized internal and external interfaces for CubeSats of all sizes. The standard covers unit-to-unit connections, platform‑to‑payload interfaces, and the external umbilical (access port) electrical interface. It also specifies the required contents of datasheets for commercial CubeSat components and platforms to support catalogued, ready‑for‑sale products.

Key topics and technical requirements

Internal interfaces

Unit-to-unit mechanical and electrical interfaces, including guidance on mounting, harness routing and grounding.
Two architectural styles: PC‑104 style (stackable PCB boards with a 104‑pin connector; Annex B) and backplane style (vertical boards inserted into a backplane; Annex C).
Requirements for clearance, mounting holes, in‑rush current mitigation, and connector availability.

Platform-to-payload interface

Mechanical connection methods, ground lines, power distribution, analogue and digital data interfaces, debugging access, EMC, fault isolation/recovery, safety and radiation considerations.

External interface

Definition of the umbilical (access port) electrical interface used for ground support and pre‑launch access.

Datasheet requirements

Detailed content requirements for unit datasheets (Section 6) and platform datasheets (Section 7), covering electrical power, communications, command & data handling, ADCS, antennas, mechanical and software information, operations, safety and reliability.

Informative annexes

Typical digital communication schemes (Annex A) and worked examples for PC‑104 and backplane implementations.

Practical applications

Facilitates interoperability between third‑party CubeSat platforms and mission payloads, reducing integration risk and schedule slip.

Helps COTS vendors publish consistent datasheets so integrators can compare and procure components reliably.

Speeds up design, assembly, integration and test (AIT) by clarifying mechanical, electrical and software interface expectations.

Useful for academic teams, smallsat manufacturers, systems integrators, test labs and procurement specialists who need predictable interfaces for rapid mission development.
