Abstract

The purpose of this paper is to describe the results of experiments undertaken to assess the potential impact of the operation of the Satellite Power System on the D and E regions of the ionosphere, and on telecommunication systems that are dependent upon the structure of the lower ionosphere. Using the high-power, high-frequency transmitter facility located at Platteville, Colorado, power densities equivalent to the Satellite Power System can be delivered to heights of 70 to 100 km above the surface of the earth. Observations of the performance of telecommunication systems that operate in the VLF, LF, and MF portions of the spectrum have been investigated during times when the ionosphere was modified with power densities comparable to the Satellite Power System and when it was not. The results obtained indicate that the Satellite Power System as currently designed with a peak power density of 23 mW/cm2 is not likely to impact in an adverse manner upon the performance of VLF, LF, and MF telecommunication systems.
