Preliminary Results of the THOR7 Propagation Experiment in the North Pole Region
International audience A propagation experiment funded by ESA with support from CNES has been deployed in Svalbard (Northern Norway, 80° latitude North) in order to study propagation impairments at Ka-band caused by the troposphere at high latitudes and low elevation angles in representative conditi...
