The terrestrial use of dynamic radios in satellites bands isn’t “technically feasible and would pose a serious threat of harmful interference to satellite networks,” the Satellite Industry Association said in comments on the FCC. The SIA was responding to a…

notice of inquiry on increasing efficient use of spectrum through dynamic use technologies. Neither real-time databases nor spectrum sensing technologies could fully protect satellite services from interference, the group said. Blanket-licensed earth stations, receive-only dishes and mobile satellite transceivers couldn’t be protected by a real-time database because accurate location information is necessary, said SIA. Spectrum sensing technologies also couldn’t protect downlinks because a dynamic radio’s “proximity to an earth station has no impact on the aggregate noise that the receiver” on a satellite receives, the association said.
