What is BS EN 16603-70-01 - Onboard control procedures in space engineering about?  
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. BS EN 16603-70-01 defines the concept for an OBCP system, identifying the onboard functionality for OBCP execution and the ground functionality for OBCP preparation and subsequent control.
BS EN 16603-70-01 also defines the development lifecycle for OBCPs and identifies the relationships of this lifecycle with the overall space system, and in particular with the other elements of the onboard software.
BS EN 16603-70-01 assumes that missions implementing OBCPs are also compliant with ECSS-E-70-41 since a number of services contained therein are invoked in support of the operation of OBCPs and their interaction with the ground.
BS EN 16603-70-01 has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g.: aerospace).
Who is BS EN 16603-70-01 - Onboard control procedures in space engineering for? 
BS EN 16603-70-01 on on-board control procedures in space engineering is useful for: 
- Spacecraft and space products manufacturers         
- Aerospace products manufacturers   
- Testing agencies involved in the inspection of spacecraft and aerospace products         
- Quality control personnel for spacecraft products      
- Aeronautical engineers 
- Space researchers
Why should you use BS EN 16603-70-01 - Onboard control procedures in space engineering?  
On-board control procedures (OBCPs) have been implemented on an ad-hoc basis on several European missions over the last 25 years, so the validity and utility of the concept have been amply demonstrated.
The purpose of BS EN 16603-70-01 is to define an OBCP concept that can be applied for any mission and which:
- Fulfils the needs of all categories of users (system engineers, on-board software engineers, AIT engineers, operations engineers)
- Ensures that OBCPs have a development lifecycle that is independent of the remainder of the onboard software (OBSW)
- Conforms with, and extends, existing ECSS monitoring and control standards, namely ECSS-E-70-41 and ECSS-E-ST-70-31.
BS EN 16603-70-01 may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.
