Abstract: Technical information relevant to the solution of frequency sharing problems in the VHF band that are associated with the use of VHF for the aircraft/ satellite link of a synchronous satellite air traffic control system is included in this report. Specifically, estimates are given of (l) the desired-to-undesired RF signal ratios available at the satellite when interference from a multitude of conventional air traffic control facilities is considered, and (2) the extent to which the service range of conventional air traffic control facilities may be reduced because of interference caused by transmissions from a satellite. The results are applicable to either co-channel or adjacent channel interference problems, and may be easily modified to accommodate a variety of system parameter changes.
