A methodology for the selection of frequencies for deep space telecommunications

For each new deep-space mission it is necessary to select the radio frequencies that will be used for uplink and downlink communication. The frequency selection has the objective of avoiding or minimizing the possibility of radio interference between existing and planned missions. This paper presents a comprehensive procedure for the selection of frequencies for deep-space communications. The procedure includes the possible effects of several existing missions on a new mission. This is shown through an example of frequency selection of a new National Aeronautics and Space Administration (NASA) deep-spce mission using actual mission data.
