ABSTRACT:
The Disaster Warning Communications System is a message relay system designed to provide backup warning of impending natural hazard in areas where normal communications are vulnerable to losses imposed by geographic influence. It has been designed to take advantage of the near-hemispheric communications access of existing geostationary weather satellites. This broad coverage allows a single satellite to provide warning to virtually all the inhabited islands in the hemisphere surrounding the subpoint of the satellite, excluding only the extreme polar areas. By extension, three such satellites can cover the entire populated Earth.
