European Space Agency

“To provide for and promote, for exclusively peaceful purposes, cooperation among European states in space research and technology and their space applications.” Procurement Agency: About 85% of ESA’s budget is spent on contracts with European industry Areas: Space science Human spaceflight Exploration Earth observation Launchers Navigation Telecommunications Technology Operations

ESA’s industrial policy:

1. ensures that Member States get a

fair return on their investment; 2 . im proves com petitiveness of European industry;

3. maintains and develops space

technology;

4. exploits the advantages of free

competitive bidding, except where incompatible with objectives of the industrial policy.

Question

After 10 years, what about ESA SW process assessment? I t is sound – Supporting and aligned to other ECSS – Consistent deployment – Adapted to the criticality of the software I t is required – Software projects risk management tool – Space Software industry in a maturity stage  process innovation and improvement, more efficient in order to enhance competitive advantage – New firms in the space software industry – introduction to ESA requirements
