Absolute distance metrology for space interferometers

Autor: Swinkels, B.L., Bhattacharya, N., Wielders, A.A., Braat, J.J.M.

Publikováno v: Proceedings of SPIE, 2005 vol. 5856

Future space missions, among which the Darwin Space Interferometer, will consist of several free flying satellites. A complex metrology system is required to have all the components fly accurately in formation and have it operate as a single instrume

Due to the 10 microarcsecond accuracy, with which GAIA will measure the positions of stars using 2 astrometric telescopes, stability requirements on the payload module are extremely stringent. In order to achieve the required 10 microarcsecond accura
