Raumfahrtproduktsicherung - Bordseitige Kontrollprozeduren This European Standard was approved by CEN on 23 November 2014.
CEN and CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN and CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN and CENELEC member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.
CEN and CENELEC members are the national standards bodies and national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

This Standard 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. This Standard may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.

NOTE
Depending on the context, OBCP can refer to an OBCP in program source code form, or in OBCP code. 3.2.3 OBCP code complete representation of an OBCP, in a form that can be loaded on-board for subsequent execution NOTE 1 In previous missions, such code is typically referred to as token code, executable code or bytecode depending on the implementation of the relevant OBCP engine.
