B3 (AI 1.21) - Compatibility between the Radio Astronomy Service and Active Space Services

Background

WRC-03 adopted Resolution 739, which defines a consultation process for select radio astronomy/active space service band pairs to assist administrations in reaching mutually acceptable solutions when unwanted emissions from space services exceed specified levels in certain radio astronomy bands. WRC-03 also adopted Resolution 740 to expand the consultation process to some other band pairs, taking into consideration the results of ITU-R studies.

After extensive discussions, WRC-07 agreed to expand the consultation process to all of the band pairs for which studies have been concluded within the ITU-R.

Discussion

The implementation of this WRC-07 decision in Canada complements a mechanism adopted by WRC-03 to ensure compatibility between Canadian radio astronomy stations and active space stations operating in the bands listed in footnote No. 5.208B, as modified by WRC-07.
