Abstract
This article reviews the transmission losses due to different propagation modes given in the Recommendation ITU-R P. 452-14, and derives a general lower bound for the ducting loss. This derived lower bound for the ducting loss is applied to the European Space Agency (ESA) Cebreros deep-space station. In addition, the results of a statistical study of the ducting losses for the Cebreros deep-space station are given. The results indicate that the ducting loss may become smaller than the troposcatter and diffraction losses for separation distances less than 10 km. Since, for most cases, the separation distances between the transmitters and the deep-space station receiver are expected to be greater than 10 km, only the troposcatter and diffraction losses need to be considered in interference analyses, and the ducting losses can be neglected.
