Proba-3 is ESA's first precision formation flying space mission. The objective is to demonstrate how small satellites, in combination with formation flying technology, can achieve relevant scientific goals and perform scientific measurements not possible otherwise.
This technology—a combination of small independent platforms—is easier to launch and can replace bulky structures, such as telescopes, and work as a single entity while achieving high performance. The application of formation flying technology would be of great interest in a wide range of missions, including X-ray astronomy and optical or IR interferometry missions.
At Sener we are spearheading the Proba-3 mission, in close collaboration with an industrial team consisting of Redwire Space, Airbus Defence and Space in Spain, GMV Space and Defence, and Spacebel, which encompasses a large consortium of more than 29 companies from 17 countries.
This is the first time that a Spanish company has led the full development of an ESA mission (meaning it is responsible for both the ground and flight segments).
