RAFCAP meeting 2008

2008 Feb 14 RAFCAP 2008 in Pune 4

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”



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


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


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


Modifications to FN 5.347A

5.347A In the bands:

137-138 MHz,

387-390 MHz,

400.15-401 MHz,

1 452-1 492 MHz,

1 525-1 559 MHz,

1 559-1 610 MHz,

1 613.8-1 626.5 MHz,

2 655-2 670 MHz,

2 670-2 690 MHz,

21.4-22 GHz,

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


For GSO stations (in pfd)


For Non-GSO stations (in epfd)


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;



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.



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

See AI1.21 2008 Feb 14 16RAFCAP 2008 in Pune


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);


WRC-07 Agenda Item 1.8 (contd.)

Separation distance between a RAS station and the nadir of a HAPS platform was determined to be 50 km in Resolves 5 of Resolution 122 (Rev. WRC-07)


WRC Agenda Item 7.2

Discussion of Future Agenda Items for WRC-11 and WRC-15

26 agenda items have been identified for WRC-11, together with several permanent agenda items

Detailed will be presented later
