Description

Resolution 743 [COM5/7]

This resolution relates to the band 42.5 - 43.5 GHz, where power flux density (PFD) limits were introduced to protect the radio astronomy service from emissions from GSO FSS and BSS systems. In article 5.BC05 these are defined as absolute (100% of time) levels, but in this resolution it states that in Region 2 they can be exceeded for not more than 2% of time. However it also calls for studies and development of Recommendations to establish the appropriate balance between this percentage of time and the associated impact on radio astronomy observations.
