1 Scope

China's national standard for the software architecture of spacecraft information systems. Spacecraft software has become the dominant source of both capability and risk in a mission: the vehicle's autonomy, its fault management, its instrument control and its data handling are software, and the well-known failures of the last decades have been software failures rather than mechanical ones. An architecture standard addresses that at the level where it can be addressed - by fixing how the software is structured, how its components communicate, how the flight-critical parts are separated from the rest, and how the system behaves when a component fails. The separation is the crucial provision: an architecture in which a payload application can affect the attitude control is one where an experiment can lose the spacecraft, and that has happened.

This document specifies the spacecraft information system software architecture, interfaces and operating system layer, middleware layer, application layer in the software architecture: Use the composition of management: This document applies to the software system design, software architecture and software component design of the spacecraft information system:
