Interferometry in Space

Our department plays the leading role in the development of the space-based gravitational-wave detector LISA (Laser Interferometer Space Antenna). LISA technology also flies onboard the GRACE Follow-On mission, which observes climate change trough changes in the Earth's gravitational field. The department also was a major player in the LISA Pathfinder mission, which successfully tested key technologies for LISA from 2015 until 2017.

LISA will be a mission of discovery – the first gravitational-wave observatory in space. It will gather entirely new information about the dark, invisible Universe and work hand in hand with other astronomical observatories in the 2030s. [more]
GRACE Follow-On observes critical indicators of climate change through changes in Earth's gravitational field using LISA technologly. The mission uses a laser interferometer between two satellites with nanometre-level accuracy. [more]
LISA Pathfinder was the test mission of the European Space Agency ESA for LISA,  the first gravitational wave observatory in space. LISA Pathfinder successfully demonstrated central LISA technologies. [more]
AEI is the largest laboratory worldwide for LISA interferometry. We cover the widest range of technologies while keeping close contact to all other participating groups. [more]
LTPDA is a freely available MATLAB-based toolbox which we are developing for LISA Pathfinder data analysis. It is highly useful for other data analysis applications as well. [more]
