Sensitivity of Satellite Interference to Locations of Small-Aperture Terminals

Interference to adjacent satellites depends on the specific location of the interfering satellite terminal, and this is an important issue in the case of vehicle-mounted Earth stations (VMES), which use small-aperture antennas. Anticipating large-scale deployments of VMES, regulatory and standards agencies are currently establishing regulations and requirements for VMES. A conventional Earth terminal is required to operate at a fixed location, which could be a very small area around a specific point. Because VMES are mobile, current location-specific regulatory requirements applicable to stationary satellite terminals are not appropriate for VMES. Before establishing suitable location-specific regulations and requirements on VMES, it is necessary to investigate the sensitivity of the interference to the locations of the VMES. In this paper, we provide a detailed investigation of the effects of the locations of the VMES on adjacent satellite interference.
