The ESA DARWIN project uses a set of telescopes based on free flying satellites and operated as an aperture synthesis system. The relative position of all these satellites has to be maintained with a very high accuracy. This is only possible with the

Publikováno v: SPIE Proceedings.

ESA’s DARWIN mission is to accomplish the unprecedented challenge of finding Earth-like planets orbiting nearby stars. To tell apart the planet from its blinding ‘sun’, the system relies upon nulling interferometry: the light collected by six free
