A system and method allow end users the ability to operate using non-compliant antennas. A coordination database may be continually updated with respect to geographic coordinates, time planning, frequency and orbital positions. Further, the system and method may utilize a tool for easily calculating interference resulting from the use of non-compliant antennas. These components, amongst others, spot possible slots in the frequency spectrum for non-compliance operations. A device may be integrated into terrestrial terminals to perform a sound, realistic and up-to-date interference calculation for equipment in a particular environment. The device may determine the level and extent of safety for operating the equipment in the particular environment.
