Version history

Version evolution

The 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.

Recommends

  1. that the transmission characteristics and data formats for a satellite EPIRB operating through a satellite system in the 406 MHz band should be in accordance with Cospas-Sarsat Document C/S T.001 (Issue 3, Revision 10, October 2009 titled Specification for 406 MHz Cospas-Sarsat Distress Beacons).
  2. NOTE 1 – A copy of document C/S T.001 (Issue 3, Revision 10, October 2009) can be obtained free of charge from the Cospas-Sarsat Secretariat (mail@cospas.sarsat.int) or the Cospas-Sarsat website (http://www.cospas-sarsat.org/).
