Impact of Satellite Power System (SPS) heating on VLF, LF, and MF telecommunications systems ascertained by experimental means
Abstract
Using the high-power high-frequency transmitter facility located at Platteville, Colorado, power densities comparable to the Satellite Power System (SPS) can be delivered to the 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 were investigated during times when the ionosphere was modified with SPS comparable power density and when it was not. The results obtained indicate that the SPS, as currently configured with a peak power density of 23 mW/sq cm, will not adversely impact upon the performance of VLF, LF, and MF telecommunication systems.
