DLR to use Airbus Bartolomeo Service for First-Ever In-Orbit Verification of Laser-Optical Clocks

By GeoConnexion - 28th April 2021 - 13:53

The Galileo Competence Center of the German Aerospace Center (DLR-GK) and Airbus have signed a €16.8 Mio contract for the hosting of DLR’s COMPASSO mission on the International Space Station (ISS) Bartolomeo platform. COMPASSO will be the first in-orbit verification of compact and highly stable laser-optical clocks. Via a bi-directional optical link, these clocks are compared to and synchronized with highly stable clocks on Earth. In addition, the optical link between the ISS and the ground station is used for assessing the influence of atmospheric turbulence on the frequency and time transfer. In combination with optical links, highly stable optical clocks are of particular interest for future generations of satellite navigation systems, such as Galileo, and the basis for new Global Navigation Satellite Systems (GNSS) architectures, such as the Kepler concept developed at DLR. www.airbus.com
