All IBR Recommendations

As incorporated in RR-2016

This is not the text in force. It is the version of this Recommendation that RR-2016 gave treaty-binding force, kept so that the incorporated set can be read as it stood at each conference.

Recommendation ITU-R SA.1154-0

Mandatory (1995)

Provisions to protect the space research (SR), space operations (SO) and Earth-exploration satellite services (EES) and to facilitate sharing with the mobile service in the 2 025-2 110 MHz and 2 200-2 290 MHz bands

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.

Footnote

5.391

Bands and services are derived from the footnotes of the Radio Regulations as they stand, so they are shown only on the edition in force.

Scope

the bands 2 025-2 110 MHz and 2 200-2 290 MHz are allocated on a primary basis to three of the space science services (SR, SO, EES), the fixed service (FS) and the mobile service (MS) subject to the provisions of Nos. 5.391 and 5.392 of the Radio Regulations (RR);

Recommends

  1. that the following provisions are suitable to protect the SR, SO and EES services from aggregate interference from emissions of mobile systems in the 2 025-2 110 MHz band:
  2. 1.1 that the aggregate interference at the input terminals of the spacecraft receiver, except in the case of a space-to-space link, should not exceed –180 dB(W/kHz) for more than 0.1% of the time;
  3. 1.2 that in the case of space-to-space links the aggregate interference at the input terminals of the spacecraft receiver should not exceed –184 dB(W/kHz) for more than 0.1% of the time;
  4. that the following provisions are suitable to protect the SR, SO and EES services from aggregate interference from emissions of mobile systems in the 2 200-2 290 MHz band:
  5. 2.1 that the aggregate interference at the input terminals of the receiver in the earth station should not exceed -216 dB(W/Hz) for more than 0.1% of the time;
  6. 2.2 that the aggregate interference at the input terminals of the DRS spacecraft receiver should not exceed -184 dB(W/kHz) for more than 0.1% of the time;
