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.
