Abstract

A system, method, and apparatus for integrated resource planning for satellite systems are disclosed. The method involves obtaining user communication demand for at least one region. The method further involves generating a beam map comprising at least one beam for each of the regions according to the user communication demand. Also, the method involves generating at least one configuration profile for the satellite system by using the beam map. Additionally, the method involves performing a performance analysis by comparing: the user communication demand versus one of the configuration profiles, the user communication demand versus actual communication demand, one of the configuration profiles versus the actual communication demand, and/or one of the configuration profiles versus another one of the configuration profiles. Further, the method optionally involves determining power flux spectral density (PFSD) for the beam frequency spectrum for each of the beams by using at least one of the configuration profiles.
