Abstract

The world has recently been hit by severe natural disasters. This, and the general development with more tasks for defence and civil security authorities outside the national borders have led to increased awareness that access to rapid, reliable and independent information at high spatial resolution from any arbitrary location on the Earth is of highest importance to support national and international crisis management. 

This development is evident in Sweden, and consequently the Swedish government and defence authorities plan for the development of a national satellite observation capability. SVEA is a novel Earth Observation satellite concept, developed by Swedish Space Corporation, to answer to this need. SVEA is based on the ongoing PRISMA spacecraft development, which includes several new features in satellite design, building on the experience from the SMART-1 lunar mission and other small-satellite projects. 

This paper discusses the design aspects of this small-size surveillance satellite. Maximum re-use and strict control of spiralling requirements are key to make the spacecraft affordable. Yet, Svea is a very agile high resolution observation system, ideal for a small country that is in the need for rapid and independent geospatial information.
