SpaceTech GmbH - small satellite mission MERLIN

eagleyard Photonics GmbH enables SpaceTech GmbH/Immenstaad to build the LIDAR Frequency Reference Unit for German-French small satellite mission MERLIN (Methane Remote Sensing LIDAR Mission) - Helping measuring methane gas concentration for a better understanding of climate change.    

With a scheduled launch for 2021, the German-French satellite mission is laid out to measure methane gas concentration by means of a LIDAR instrument (LIght Detection And Ranging) sending laser light pulses into the atmosphere and determining the gas concentration by the characteristics of the reflected light.
