With increasing utilization of satellite mobile services capacity shortage in respectively common frequency bands (L band) is to be expected. To enhance understanding of propagation channel characteristics at higher frequency bands (Ku/Ka band) an experiment with a mobile receiver, using narrow- and wideband test signals has been carried out. An airborne test platform has allowed to consider real satellite incidence angles. A comprehensive database has been obtained on channel behaviour and - by means of auxiliary instruments -documenting the details of four typical scenarios measured. Preliminary results indicate excellent qualitative plausibility, such as recognition of electricity poles. Ongoing quantitative analyses include comparisons to literature, e.g. specific attenuation in vegetation. Focus is a statistical analysis to set up a channel simulator predicting the propagation channel characteristics under the measured scenarios' conditions. It is planned to submit results for standardization.
