Spirale, the space-borne early warning system: two million images collected in its first year of operations by Airbus Defence and Space

  • The demonstrator has already surpassed the initial goals of the DGA

  • Thanks to its excellent performance, the Spirale mission will be extended beyond its initially planned duration

 

Toulouse, 15 June, 2010 Airbus Defence and Space recently completed its first full year of operations with the Spirale system, following its acceptance in April 2009 by the DGA (French armament procurement agency). The acquisition and analysis of infrared satellite data has been a complete success. Airbus Defence and Space acted as prime contractor for the design and development of Spirale, which uses two micro-satellites from the Myriade product line to collect infrared images against land and cloud backgrounds from a geostationary transfer orbit (GTO).

 

Despite the harsh environment of its orbit, which passes through the Van Allen radiation belt, Spirale has surpassed the objectives of the demonstration phase, both in terms of the volume and the level of detail of the acquired data. In its first year in orbit, Spirale collected more than two million images.

 

"We've now established precise characteristics for radiation from a wide variety of backgrounds and natural phenomena, such as sunlight reflected off clouds," explained Jean Dauphin, Director Earth Observation and Sciences at Airbus Defence and Space France. "This has allowed us to identify potential sources of false alarms for missile launches and find ways to overcome them. We also have a much better understanding of how these phenomena can hinder the detection of ballistic missile launches."

The results have convinced the French defence ministry that the space-borne early warning system is capable of obtaining the data required to detect and locate ballistic missile launches. The demonstrator’s now proven, excellent reliability has also made it possible to extend its original mission life, permitting the collection of even more images and a more detailed analysis of the performance that can be expected from a fully operational space-borne warning system.
