Nanometer ranging systems for low Earth orbiter links (B06)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas ; Geodesy, Photogrammetry, Remote Sensing, Geoinformatics, Cartography
• Term: from 2014 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 239994235

Project B06 has the goal of creating performance models, noise budgets and experimental prototypes for future missions similar to the Gravity Recovery And Climate Experiment Follow-On mission (GRACE-FO). Here, emphasis lies on the laser interferometry along the long arm in contrast to the local effects, which are studied in other geo-Q projects. In particular, we will experimentally study new interferometer topologies and the initial acquisition problem.
