October 2010 and September 2012 two airship flight campaigns for GNSS
reflectometry (GNSS-R) were organized by GFZ in cooperation with DLR
and Zeppelin Luftschifftechnik (ZLT). The flights were performed in
the Lake Constance region near Friedrichshafen, Southern Germany.
Flight platforms offer a better spatial coverage of the GNSS-R
observations compared to the ground based data. In addition the
equipment was tested for succeeding flight campaigns with the German
research aircraft HALO. Furthermore the flight experiments are a
crucial step for future satellite based reflectometry measurements for
remote sensing on a global scale.
The Zeppelin airship is a relatively slowly moving platform (<100km/h) and has an excellent. Therefore it can quite easily pilot height anomalies on the rather small lake surface. Initial reflectometry results based on Doppler measurements aboard the Zeppelin were published in 2013 .
