ATS-6 satellite 20 GHz propagation measurements at low elevation angles

Abstract
The 20 GHz downlink from the ATS-6 satellite was monitored almost continuously for low elevation angles (below 9°). The authors measured the copolarised and crosspolarised signals received, as well as the local rain rate. Data are presented for clear-weather scintillations, rain attenuation, depolarisation and other effects.
