What is BS EN 16603-60-30 - Satellite AOCS requirements about ?  
BS EN 16603-60-30 specifies a baseline for the attitude and orbit control system requirements to be used in the Project Requirements Document for space applications.
BS EN 16603-60-30 deals with the attitude and orbit control systems developed as part of a satellite space project. The classical attitude and orbit control systems considered here include the following functions:
- Attitude estimation
- Attitude guidance
- Attitude control
- Orbit control
- Orbit estimation, called Navigation in this document, can be part of the function for missions that explicitly require this function
- Acquisition and maintenance of a safe attitude in emergency cases and return to the nominal mission upon command
Note: BS EN 16603-60-30 does not cover missions that include the following functions:
- Real-time on-board trajectory guidance and control
- Real-time on-board relative position estimation and control

Why should you use BS EN 16603-60-30 - Satellite AOCS requirements ?  
The Attitude and Orbit Control System (AOCS) requirements for the development of space programmes are typically part of the Project Requirements Document. The level of completeness and the level of detail vary very much from project to project.
BS EN 16603-60-30 provides a baseline for the AOCS requirements which are used in the specification and the validation process.
BS EN 16603-60-30 is intended to be used for each programme as input for writing the Project Requirements Document. It includes all subjects related to AOCS:
- Functional and FDIR requirements
- Operational requirements
- Performance requirements
- Verification requirements
- Documentation requirements
BS EN 16603-60-30 may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.
