Smart satellites in Smart Grids

Abstract

Satellite services for users in smart grids may be studied from the perspectives of market and technology. Economic variation has led to the transition of satellite communications services among different spectrum segments. The short-term demand for capacity drives the potentially increased use of satellites operating in high frequency band. However, satellite transponders at moderate frequency band may enjoy lower cost as compared with its counterpart in higher frequency band. There have been many satellites covering different service areas, which may constitute a considerable amount of revenue in satellite services. On the other hand, some satellite communication terminals may be manufactured and installed in order to use some waveforms. Satellite communications systems shall enable satellite operators to service users that employ some waveforms via satellite transponders. Hence the transponders may become accessible for the ground terminals. The operators of satellite communications systems may use a given satellite transponder to service users employing some waveforms within the spectrum of interest.
