Sharing in the 1-3 GHz frequency range between non-geostationary space stations operating in the mobile-satellite service and stations in the fixed service
Levels of power flux-density (pfd) and fractional degradation in performance are presented as thresholds for coordination of frequency assignments for non-geostationary orbit (non-GSO) space station transmitters in the mobile-satellite service MSS and receiving stations in the fixed service (FS) in frequency bands shared between these services in the 1-3 GHz frequency range. In the annexes, the methodology for sharing between constellations of non-GSO space station transmitters and receiving fixed stations is described and a summary of studies of frequency sharing between transmitting fixed stations and non-GSO space station receivers is presented.
