ISO 16615:2025

This document provides the criteria for stable on-orbit operation of the spacecraft's AOCS. It addresses the factors affecting the spacecraft's on-orbit stability by specifying principles and requirements for establishing the spacecraft AOCS's capability for stable on-orbit operation, which include: — principles for judging data validity and the requisite procedures for handling such data; — anomaly detection; — management of software and hardware failures; — safety boundary checks; — activation protocols for emergency survival modes. This document also establishes the functional interface between on-orbit autonomy and ground-based maintenance operations, ensuring that the spacecraft maintains its intended attitude and orbit. This document is applicable to the attitude and orbit control systems of various types of spacecraft.
