The Prediction of Weather Effects on Telecommunications Link Performance,iption of weather effects. The measured effects of weather, namely atmospheric attenuation and increase in ground receiver system noise temperature, are additive (in decibels). The combined probability density function is therefore the convolution of the separate density functions.

Radio Frequency Selection and Interference Prevention,freedom from interference. Radio frequencies for deep-space research may be chosen from bands that are allocated for that purpose. The choice of particular frequencies within those bands is guided mostly by the need to avoid interference between deep-space missions. Interference may also result from
