The Future Satellite Business Is Small Satellite Business

Abstract

The small satellite initiative created by NASA about 10 years ago was to capitalize on space experience in terms of cost reduction. In the meantime, many missions sharing the “faster, better, cheaper” slogan have evolved — with mixed results. In this paper, Astrium’s interpretation of the small satellite slogan is explained, e.g., that “small” means small in cost but not necessarily small in size or mass. Consequently, it will be shown how Astrium — as a leading space company with a reputation of nearly 100% in-orbit success — achieves low costs while maintaining quality, reliability and performance.

An overview of small satellite platforms developed for several market segments is given together with an insight view of the FlexBus — a concept based on standardized modular construction aiming for mission tailored low cost satellites. Finally, a classification of conventional “large” satellites, “small” (low cost) satellites, “micro-” and “nano-” satellites is given. Based on examples of current and future programs a clear market trend towards smaller satellites can be demonstrated, while a more reserved assessment of the market potential for micro- and nano-satellites is shown. Micro-satellites will stay focused on universities or pave the way on export markets, while nano-satellites will remain a technological target, with no significant business in the near future.
