Protection of fixed service receivers from the interference produced by the non-geostationary satellites in a fixed satellite service network: a statistical interference analysis

摘要

Until 1997, the power flux density(pfd)limits applicable to fixed satellite service(FSS)satellite transmitters to protect fixed service(FS)receivers operating in the same frequency band were those in Article 21 of the radio regulations. They were developed assuming that potentially interfering satellites in the FSS would only operate in the GSO. The need to revise these limits to allow for the protection of Fs receivers from interference generated by non-geostationary satellites has led to several studies, most of them based on the non-realistic assumption that every visible satellites in a NGSO constellation produces the maximum allowed pfd level at the FS receive station location.
