WRC-07 Agenda Item 1.17  1.17to 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 MHz (Earth-to-space) and MHz (space-to-Earth) WP8D: draft CPM text suggests to suppress these allocations. FCC: the satellite operator disappeared Feb 145RAFCAP 2008 in Pune

Results for AI 1.17 Suppression of FN 5.379A and Resolution A Additional allocation: the band MHz is also allocated to the fixed-satellite service (Earth-to- space) on a secondary basis and the band 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” 2008 Feb 14RAFCAP 2008 in Pune7

WRC-07 Agenda Item 1.21  1.21to 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 148RAFCAP 2008 in Pune

Historical Landmarks 1968Discovery of OH-IR sources 1979OH 1612-MHz line given secondary allocation 1982First GLONASS satellite launched (military) 1983Coordination of GLONASS begins 1985Interference identified and published IRAS catalogue published (~104 OH-IR sources) 1991First IUCAF-GLONASS meeting 1992Worldwide experiment to test possible cures Radio astronomy band made primary 1993GLONASS-IUCAF Agreement signed in Moscow 2006Projected completion of “clean-up” plan 2008 Feb 14RAFCAP 2008 in Pune9

GLONASS-IUCAF Agreement Coordination is possible with radio astronomy 1993 onwards, no satellites in channels onwards, satellites confined to channels 1-12 New GLONASS frequency plan is needed Filters will be installed on GLONASS-M satellites, sufficient to protect MHz 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 2008 Feb 14RAFCAP 2008 in Pune10

Modifications to FN 5.347A 5.347A In the bands: MHz, MHz, MHz, MHz, MHz, MHz, MHz, MHz, MHz, GHz, Resolution 739 (Rev.WRC-07) applies. (WRC-07) 2008 Feb 1411RAFCAP 2008 in Pune

For GSO stations (in pfd) 2008 Feb 14RAFCAP 2008 in Pune12

For Non-GSO stations (in epfd) 2008 Feb 14RAFCAP 2008 in Pune13

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; 2008 Feb 14RAFCAP 2008 in Pune14

WRC-07 Agenda Item 1.7  1.7to consider the results of ITU-R studies regarding sharing between the mobile- satellite service and the space research service (passive) in the band MHz, and between the mobile-satellite service and the mobile service in the band 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 Feb 1415RAFCAP 2008 in Pune

WRC-07 Agenda Item 1.11  1.11to review sharing criteria and regulatory provisions for protection of terrestrial services, in particular terrestrial television broadcasting services, in the band MHz from BSS networks and systems, in accordance with Resolution 545 (WRC ‑ 03); Protection from BSS space stations RAS: MHz will be appropriately protected See AI Feb 1416RAFCAP 2008 in Pune

WRC-07 Agenda Item 1.8  1.8to 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 GHz and 31 ‑ 31.3 GHz in response to Resolution 145 (WRC ‑ 03), and for high altitude platform stations operating in the bands GHz and GHz in response to Resolution 122 (Rev.WRC ‑ 03); 2008 Feb 1417RAFCAP 2008 in Pune

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) 2008 Feb 1418RAFCAP 2008 in Pune
