Objectives of ITU-R

•Global coordination of radiocommunications

•ITU Radio Regulations

•International Spectrum Management

•Frequency Plans

Objectives of ITU-R

•Global coordination of radiocommunications

•International focal point for standardization of wireless systems

Recommendations - de facto Standards on:

•spectrum management issues

•radiocommunication system characteristics and operation

Example topics:

•radiowave propagation

•wireless access systems

•EESS systems

•broadcasting

Objectives of ITU-R

To promote the development and use of

radiocommunications for the benefit of all

•Global coordination of radiocommunications

•International focal point for standardization of wireless systems

•Promote the world-wide development of radiocommunications

ITU-R Objective

Objective achieved through (inter alia):

• World and Regional Radiocommunication Conferences

• Approval of Recommendations by Member States by correspondence at Radiocommunication Assembly

Technical studies are requiredwhich are conducted in Study Groups

ITU-R Study Groups

• Groups of experts (> 1500)from ITU membership

• Develop technical bases for WRCs and RRCs

• Develop Recommendations technical characteristics operational procedures

• Compile Handbooks

ITU-R Study Groups

SG 1: Spectrum managementSG 3: Radiowave propagationSG 4: Fixed-satellite serviceSG 6: Broadcasting serviceSG 7: Science servicesSG 8: Mobile servicesSG 9: Fixed service

ITU-R Study Groups

• Currently 7 Study Groups• Subordinate groups

Working Party Task Group Rapporteur Group Joint …….

• Coordination Committee for Vocabulary• Special Committee (regulatory/procedural)• CPM - Conference Preparatory

Meeting

Radiocommunication Assembly

• Establishes ITU-R Study Groups (and elects their chairmen/vice-chairmen)

• Adopts SG work programmes• Approves Recommendations• Approves Resolutions

working procedures specific aspects of SG responsibility

Scope of Study Group 7(Science services)

• Systems for space operation, space research, Earth exploration and meteorology

• Radio astronomy• Standard frequency and time signals

SG 7- some key areas of study -

Chapter 2 of CPM Report

Space science servicesRapporteur: Mrs. Shayla Taylor (USA)

WRC-07 Agenda items

1.2, 1.20, 1.21

1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and Meteo-Sat in 18.1 – 18.4 GHz, 10.6 – 10.68 GHz and 36 – 37 GHz

1.20: Protection of EESS (passive) (bands 1400 – 1427 MHz, 23.6 – 24 GHz, 31.3 – 31.5 GHz, 50.2 – 50.4 GHz) from unwanted emissions of active services

1.21: Compatibility between RA and active space services (bands referred to in Res740) in order to review and update the threshold levels used for consultation (Annex to Res739)

AI 1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and MetSat in 18.1–18.4 GHz,

10.6–10.68 GHz and 36–37 GHz (1)Current results of studies (18.1-18.4 GHz):

• the addition of 100 MHz seems feasible under certain conditions (but compatibility between MetSat and NGSO FSS not studied);

• proposes additional allocation, either 18.0-18.1 or 18.3-18.4 GHz;

• indication that 18.0-18.1 GHz option may impose minor constrains on MetSat orbital positions due to operation of BSS feeder-links of networks belonging to Regions 1 and 3 BSS Plans/Lists (Appendix 30A)

AI 1.2: Allocations and related regulatory issues for EESS (passive), SRS (passive) and MetSat in 18.1–18.4 GHz,

10.6–10.68 GHz and 36–37 GHz (2)

Current results of studies (10.6-10.68 GHz and 36-37 GHz):

• interference from FS in 10.6-10.68 GHz band may exceed limits for EESS sensors by ~17 dB; mitigation therefore necessary;

• preliminary sharing criteria proposed for 36-37 GHz band, but not to be applied to terrestrial systems brought into use before WRC-07

AI 1.20: Protection of EESS (passive) (bands 1400 – 1427 MHz, 23.6 – 24, 31.3 – 31.5, 50.2 – 50.4 GHz) from unwanted

emissions of active services

Current results of studies:

• TG 1/9 revising Rec. ITU-R SM.1633, which should be used as a basis for developing EESS protection criteria;

• proposed to include unwanted emission power [limit /level] in RR; sensors protected but some limitation on future active systems;

• still at a preliminary stage.

AI 1.21: Compatibility between RA and active space services (Res.740) in order to review and update threshold

levels used for consultation (Annex to Res.739)

Current results of studies:• proposed PFD threshold levels for RAS

protection from interference from different services;

• 3 methods are under consideration: 1st –add approved thresholds in Res.739 and

apply them (RAS protected, but more work for ADMs due consultation);

2nd similar to 1st but RNSS is not covered (no burden for ADMs but RAS may not be protected in 1559-1610 MHz);

3rd no incorporation of thresholds (TBD).
