Prediction of RF environments worldwide for ground, airborne, and space launch trajectory applications via automated database

The evaluation of the radio frequency (RF) environment for electronic systems in the field has often been a time consuming and burdensome task, especially for mobile systems. This paper discusses a methodology for determining the RF environment for such systems using common office spreadsheet software. The model developed has been validated and used successfully to evaluate the RF environment on the ground and during ascent for several launch vehicles, launch sites, and payloads.
