WRC 2007 Results
October 22 ~ November 16, 2007Geneva, Switzerland
Masatoshi OHISHI
RAFCAP meeting 2008
WRC-07 Agenda Item 1.17
1.17 to consider the results of ITU-R studies on compatibility between the fixed-satellite service and other services around 1.4 GHz, in accordance with Resolution 745 (WRC‑03);
MSS feeder links operating in the bands 1 390-1 392 MHz (Earth-to-space) and 1 430-1 432 MHz (space-to-Earth)
WP8D: draft CPM text suggests to suppress these allocations.

Results for AI 1.17
Suppression of FN 5.379A and Resolution 745
5.339A Additional allocation: the band 1 390-1 392 MHz is also allocated to the fixed-satellite service (Earth-to-
space) on a secondary basis and the band 1 430-1 432 MHz is also allocated to the fixed-satellite service (space-to-
Earth) on a secondary basis. These allocations are limited to use for feeder links for non-geostationary-satellite
networks in the mobile-satellite service with service links below 1 GHz, and Resolution 745 (WRC-03) applies.
Resolution 745 (WRC-03)Resolves 1 states “shall not be used until the completion of ITU-R studies on all identified compatibility issues”

WRC-07 Agenda Item 1.21
1.21 to consider the results of studies, regarding the compatibility between the radio astronomy service and the active space services in accordance with Resolution 740 (WRC-03), in order to review and update, if appropriate, the tables of threshold levels used for consultation that appear in the Annex to Resolution 739 (WRC‑03);
TG1/9 – Compatibility Studies between RAS and Satellite Services (S-E)
GLONASS was the issue, with a lot of NOs from Russia
2008 Feb 14 8RAFCAP 2008 in Pune
Historical Landmarks1968 Discovery of OH-IR sources
1979 OH 1612-MHz line given secondary allocation
1982 First GLONASS satellite launched (military)
1983 Coordination of GLONASS begins
1985 Interference identified and publishedIRAS catalogue published (~104 OH-IR sources)
1991 First IUCAF-GLONASS meeting
1992 Worldwide experiment to test possible cures
Radio astronomy band made primary
1993 GLONASS-IUCAF Agreement signed in Moscow
2006 Projected completion of “clean-up” plan
2008 Feb 14 RAFCAP 2008 in Pune 9
GLONASS-IUCAF Agreement
• Coordination is possible with radio astronomy
• 1993 onwards, no satellites in channels 16-20
• 1999 onwards, satellites confined to channels 1-12
• New GLONASS frequency plan is needed
• Filters will be installed on GLONASS-M satellites, sufficient to protect 1660-1670MHz band
• GLONASS administration will investigate ways to fully protect 1612-MHz band and will communicate their proposed solution at a future meeting
• IUCAF will coordinate further joint experiments as needed

Resolution 739 (Rev.WRC-07) applies. (WRC-07)

Registration needed !
Any RAS station that has been registered to the ITU master register earlier than the registration of a satellite will be protected.
Resolves 4 of Resolution 739 (WRC-07)
that the radio astronomy stations to be taken into account in applying resolves 1, 2 and 3 are those which are operating in the frequency band(s) identified in Annex 1 and which are notified before the date of reception of the advance publication information of the space station or satellite system to which this Resolution applies;

WRC-07 Agenda Item 1.7
1.7 to consider the results of ITU-R studies regarding sharing between the mobile-satellite service and the space research service (passive) in the band 1 668-1 668.4 MHz, and between the mobile-satellite service and the mobile service in the band 1 668.4-1 675 MHz in accordance with Resolution 744 (WRC‑03);
Radioastron and future space-based RAS stations with similar orbital parameters with Radioastron will be appropriately protected.

WRC-07 Agenda Item 1.11
1.11 to review sharing criteria and regulatory provisions for protection of terrestrial services, in particular terrestrial television broadcasting services, in the band 620-790 MHz from BSS networks and systems, in accordance with Resolution 545 (WRC‑03);
Protection from BSS space stations
RAS: 608-614 MHz will be appropriately protected

WRC-07 Agenda Item 1.8
1.8 to consider the results of ITU-R studies on technical sharing and regulatory provisions for the application of high altitude platform stations operating in the bands 27.5-28.35 GHz and 31‑31.3 GHz in response to Resolution 145 (WRC‑03), and for high altitude platform stations operating in the bands 47.2-47.5 GHz and 47.9-48.2 GHz in response to Resolution 122 (Rev.WRC‑03);
