This is not the text in force. It is the version of this Recommendation that RR-2008 gave treaty-binding force, kept so that the incorporated set can be read as it stood at each conference.
See the edition in force (RR-2024)Recommendation ITU-R M.1642-2
Mandatory (2003-2005-2007)Methodology for assessing the maximum aggregate equivalent power flux-density at an aeronautical radionavigation service station from all radionavigation-satellite service systems operating in the 1 164-1 215 MHz band
Version history
Version evolutionThe number in each cell (e.g. −9) is the Recommendation's revision number — the “-9” in ITU-R M.585-9, not a negative value. So −8 → −9 means the binding reference moved from the 8th to the 9th revision.

Scope
This Recommendation gives a methodology and the reference antenna characteristics for assessing the maximum aggregate equivalent power flux-density (epfd) level produced at the input of a station of the aeronautical radionavigation service (ARNS) by all radionavigation-satellite service (RNSS) systems operating in any portion of the 1 164-1 215 MHz band.
Recommends
- that the methodology in Annex 1 and the reference ARNS characteristics in Annex 2 should be used to calculate the maximum aggregate epfd produced by emissions from all RNSS systems at any aeronautical radionavigation station.
