Total Levels of Anthropogenic and Natural Microwave Electromagnetic Background in Areas with Intensive Information Servicing by Constellations of Low-Orbit Communication Satellites

Abstract

A technique for analyzing the average intensity of electromagnetic background (EMB) created near the earth’s surface by subscriber terminals of satellite communication systems which are based on constellations of low-orbit satellites has been developed. Using previously obtained results of analyzing the EMB created near the earth’s surface by radiations from the space segment of these systems, estimates have been made of the total levels of anthropogenic and natural EMB in the microwave range in areas with intensive information servicing of the population by these systems. The results obtained indicate that radiation from subscriber terminals of these systems makes the main contribution to the microwave EMB intensity near the earth’s surface, exceeding by several orders of magnitude other EMB components created by both natural sources of microwave radiation and radiation from many low-orbit satellites, generally significantly changing the physical characteristics of the habitat.
