Developed by Astrium for the DGA, the Spirale satellite system is a demonstrator
that will pave the way for the future operational space-based early warning
system. The need for this system was specified and confirmed in the French
government’s new white paper on defence and national security, and its development
is included in the French military budget law that is currently being reviewed.
The first simulations based on actual images provided by Spirale will
allow an initial estimate to be made regarding the dimensioning of the most important
macroscopic parameters, such as resolution. Early results are validating the
“demonstrator” approach adopted by the DGA, and will be confirmed and refined
over the months ahead.
The Spirale system consists of two micro-satellites from the Myriade
family, developed by the CNES and built by Thales Alenia Space. The two
satellites are flying in formation in a geostationary transfer orbit (perigee 600
km – apogee 36,000 km). Spirale also includes the ground control and mission
segments based at the Astrium site in Toulouse.
Development of the system began in January 2004 and Spirale was then deployed
in orbit during February and March 2009. This followed the successful launch of
both satellites by an Ariane launcher from Kourou, French
Guiana, on 12 February 2009.
In addition to supplying and commissioning the demonstrator for the DGA,
Astrium will continue to work on Spirale through to autumn 2010 – operating the
mission and freezing the specification for the future operational space-based early
warning system.
Astrium, a
wholly owned subsidiary of EADS, is dedicated to providing civil and defence
space systems and services. In 2008, Astrium had a turnover of €4.3 billion and
more than 15,000 employees in France,

and the Netherlands.
Its three main areas of activity are Astrium Space Transportation for launchers
and orbital infrastructure, Astrium Satellites for spacecraft and ground
segment and Astrium Services for the development and delivery of satellite services.
