航天系统 航天器姿态和轨道控制系统稳定运行要求

[中文适用范围]： 本文档提供了航天器姿态和轨道控制系统（AOCS）在轨稳定运行的标准。它通过规定建立航天器AOCS在轨稳定运行能力的原则和要求来解决影响航天器在轨稳定性的因素，包括：判断数据有效性的原则和处理此类数据的必要程序；异常检测；软件和硬件故障管理；安全边界检查；应急生存模式的激活协议。本文档还规定了在轨自主与地面维护操作之间的功能接口，确保航天器保持其预期的姿态和轨道。本文档适用于各类航天器的姿态和轨道控制系统。 [外文原描述]： 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.
