Abstract :
There are a variety of operational communication systems that are dependent upon the ionosphere, and there are others that are influenced by the ionosphere. In the dependent category, we have short-wave (i.e., MF and HF systems) and long-wave systems (i.e., VLF and LF systems). In the influenced category we have some VHF systems such as meteor-burst systems, and higher frequency SATCOM systems in the UHF and SHF bands. The paper will address various resource management issues for specified operational systems, and the relationship with aspects of space-weather will be discussed. Some examples where space-weather information is used in existing systems are presented. We also identify how space-weather information could be used in those situations where it is currently unused. We conclude with challenges facing advocates of a viable space-weather program [Goodman, J.M. Space Weather and Telecommunications.
