Synchronized measurements of L- and C-band tropospheric propagation parameters

A terrestrial radio link was established, working with two frequencies in L- and in C-band. Attenuations and differential delay were measured, with the experimental setup described. A clear correlation of these parameters is confirmed by the measurements. The potential application points towards an L- and C-band GNSS service, where differential delays inherently may be noted. They could be used for predicting path attenuations and inferences about atmospheric conditions.
