Abstract : A study program has been completed concerning the probable effects of the solar cycle minimum on the Defense Communications System (DCS). The program was divided into three phases. Phase One consisted of the accumulation, reduction, and analysis of data to determine the anticipated impact of the solar cycle minimum on selected trunks of the DCS. Phase Two consisted of the accumulation and evaluation of data on fully developed currently available means of reducing the anticipated impact, and the effectiveness and relative costs of implementation. Phase Three consisted of a review of state-of-the-art developments which may lead to improved high-frequency communications systems within the next five years. This final report summarizes the results obtained in the three phases of the program. (Author)
