Introduction This Report describes how fixed-satellite service (FSS) systems can provide disaster relief radiocommunications. When developing a new FSS system in preparation to respond to natural disasters@ the technical characteristics of the satellite(s) to be accessed should be considered in the design of such FSS system. In ?? of this Report@ the summary of system design and examples of characteristics of systems using small aperture earth stations are provided. Additionally@ since FSS systems are inherently suitable for data delivery@ they are expected to be utilized for warning operations. In ?? of this Report@ the outline of an earthquake early warning system is provided as an example of warning operations using FSS system. FSS systems operate in general on frequency bands as identified in Recommendation ITU-R S.1001.
