A standing Agenda item considering possible changes to satellite coordination, notification and recording procedures for frequency assignments pertaining to satellite networks Description • The meeting almost had a formal consensus • WRC should consider any proposals which deal with for a 5-matter compromise deficiencies and improvements in the advance publication, coordination, notification and recording procedures of the RR • But now ITU-R WP4A is later than ever for frequency assignments to space services • 1.5 meetings left to finalize draft CPM text • The Resolution invite WRCs to ensure that these RR • So how to best go from here to make it work? procedures reflect the latest technologies, as far as possible Current status of studies Next steps • 5 matters received general support to be studied as Topics, • The first focus at the next WP 4A meeting will be to based on Resolution 86 (Rev. WRC-07) agree on Topics to be considered under AI 7 • Next focus will be to draft, advance and streamline CPM text on these, noting that some matters still lack such texts 26 Public SES AI 7 positions – on the 5 supported topics The 5 matters with general support as topics In addition to supporting as topics, SES:  Supports to transfer RoP into RR RR No. 4.4  Could support measures like information gathering such as duration of use, Deficiencies in, and Improvements to the RR API, reason of invoking No. 4.4 etc, noting that WRC-23 already did a lot Notification and Recording procedures relating to  Prefers to avoid too stringent or drastic restrictions, and thereby avoiding frequency assignments to stations of space services unintended consequences to be operated under No. 4.4  Considers it crucial that 4.4 may never be interpreted as any kind of acquired priority  Supports as a typical role-model AI 7 topic  Improves the efficiency of coordination procedures, reduces workload and Coordination Arc in bands where there is none resources of administrations & BR, and possibly the use of No.11.41 (excluding 8/7 GHz and 30/20 GHz)  Considers the restricted scope is appropriate in this uniquely late stage in the WRC study cycle  Support to transfer RoP into RR with already stable draft CPM text Modification to RR Appendix 4 Revision of Resolution 553 (Rev.WRC-23)  Intends to review each proposed method when draft CPM text is available Revision of Resolution 170 (Rev.WRC-23)  Notes proposals lacking technical justification in the current proposals 27 Public SES AI 7 positions – on the ITEM* for status review The 6 ITEM* matters In addition to being cautious in considering any of them as additional Topics, SES: Opposes this initiative as topic since:  BR statistics show that such BIU/BBIU cases are rare and very specific Repeat B/BIU  there could also be valid reasons for administrations to do so  it could jeopardize the process of B/BIU of some administrations that are facing new satellites to BIU and replacements RR No. 11.41 – one letter evidencing Could accept it as a topic even if not agreeing that evidence of coordination efforts are needed, as they are already required Opposes this initiative as topic since: RR No. 11.41 – restrict submissions • 11.41 is a fundamental provision that allows administrations to notify their satellite networks and operate when completion of coordination is not possible (numerous cases) despite the efforts made Opposes this initiative as topic since:  will reopen the delicate compromise from WRC-12 on very sensitive BIU provisions of 11.44 and thereby require a lot of resources RR No. 11.44B/Capability  since additional evidencing of BIU capability is not easily drafted to make a difference nor agreed and risks leading to unreasonable restrictions being imposed on space stations used for BIU/BBIU  which in turn could jeopardize the process of B/BIU of some administrations Opposes this initiative as a topic since:  even if it theoretically should be clarified/improved, we see no realistic and reasonable way to define what BR would consider unrealistic Unrealistic gain contours  which is why this matter even if being raised in the BR Director’s 9.2 report have not lead to any agreed changed regulations Opposes this initiative as a topic since: Responsibility of Notifying  the matter is not yet well defined and address issues that have not necessarily materialized in practice Administration  for global operators working with multiple administrations, redefining or reallocating responsibility could create complexity rather than clarity 28 Public AI 7 positions – SES as part of GSOA A united industry SES summary • Proposals that were withdrawn should not be reconsidered • No new proposal should be considered at the next meeting • The compromise solution with 5 proposals already identified as topics should be maintained • 6 topics should be the maximum number of topics that can be adequately studied with the remaining time before the WRC, to not overload the study workload, as the last meeting almost agreed • Any 2 existing proposals should not be merged into one topic, as it wouldn’t reduce the overall workload • Non-retroactivity should be applied across all topics GSOA summary • Limit AI 7 to maximum 6 definitive topics, reflecting previous WP4A compromises • Study the 5 matters with general support, without reopening discussions, considering CPM deadlines • GSOA could support RR No. 11.41 as a 6th topic if strictly limited to demonstrating coordination efforts • Clearly define the scope of each topic to guide studies and avoid unintended impacts • Do not merge topics, as this does not reduce the study workload • Preserve regulatory stability and non-retroactivity 20 April 2026 Public Agenda Item 9.3: RRB Report What is it about?

Article 22.2 principles must prevail: ’NGSOs must protect GSOs.’ • By its dynamic nature, NGSOs have the operational tools to protect GSOs • By its static nature, GSOs can not implement protection measures to mitigate interference from NGSOs or to protect them The protection needs are not to be disturbed • The GSO/GSO interference environment is not representative of non-GSO/GSO • ITU-R Recs. S.1323 and S.1432 are not only political compromises and still stand • Aggregate EPFD limits are needed • Clarity and predictability interference enviroments are key for GSO operations • Interference in Ku would mean disruption of service for millions/billions of people 35 Public SES position on EPFD Limits Preserve the EPFD framework as regulatory solution The EPFD framework has numerous advantages • Well established framework, proven to work • Providing clarity on the intereference environment, crucial to design GSO links • All the regulatory tools exist today New proposed framework (throughput degradation/absolute increase in unavailability) • Based on Q/V frequency bands framework although Q/V has relative increase in unavailability • Absolute increase in unavailability means that GSO performance will be capped forever • Throughput degradation does not provide any transparency or measurability • And works only for ACM* links *ACM: Adaptive Coding and Modulation. 36 Public SES position on EPFD Limits Preserve existing EPFD limits in Ku band Ku band limits have been well scrutinized • GSO parameters are still relevant • ITU-R Recommenation S.1323 is well aligned with EPFD limits • Hundreds of links were used in the studies to derive the Ku band EPFD limits Ku band limits need an EPFD approach • A very high percentage of Ku band links operate non-ACM • Most used spectrum for GSOs • Need for clarity and predictability interference enviroment 37 Public SES position on EPFD Limits Redefine the EPFD limits in Ka band Ka band limits present apparent defficiencies • Discrepancy between upper and lower parts of the Ka band could not be explained • Difference in antenna sizes • Link with GSO protection difficult to understand • ACM technology has largely evolved Ka band to be the focus • Ka-band Reference GSO links need an update, as their parameters have largely evolved • WP4A has identified an updated EPFD derivation process • Many different players are interested in the band 38 20 April 2026 Public Looking ahead Next WRC Agenda 2031 Agenda Item 10 39 Public AI 10: The next WRC-31 C-band Data Relay (Inter-Satellite Service) Optimize use of existing GSO satellites in C-band • Inter-satellite service allocations in the 3700-4200 MHz and 5 925-6 425 MHz to enable links between NGSO and GSO • To allow GSO C-band satellites to provide data relay service for LEO satellites • Typically used for sending tasking command to earth observation satellites.

Considerations on report, which is issued shortly before the WRC efficient & economical use of spectrum & orbits AGENDA 9.2 AGENDA 10 Inconsistencies Radio Regulations Future agenda items for WRC-31 Elements for consideration under this agenda item used to be based on the ITU BR Director Report which is issued shortly before the WRC WRC-27 Implications for the ITSO Common Heritage Agenda Item 1.2 • 1.2 to consider possible revisions of sharing conditions in the frequency band 13.75-14 GHz to allow the use of uplink fixed-satellite service earth stations with smaller antenna sizes, in accordance with Resolution 129 (WRC-23) Identified impact: Potential benefit for exploitation of CH in the few orbital locations and specific frequency ranges and Intelsat networks notified as part of the CH (Intelsat 7 at 325.5E and Intelsat 8 at 328.5 E) It is not expected that there will be numerous small earth stations to be deployed with the above networks and consequently, the benefit of exploiting small earth stations would be limited. WRC-27 Implica tions for the ITSO Comm on Herita ge Agenda Item 1.4 • Possible new primary allocation to the fixed-satellite service (space-to-Earth) in the frequency band 17.3-17.7 GHz and a possible new primary allocation to the broadcasting-satellite service (space-to-Earth) in the frequency band 17.3-17.8 GHz in Region 3 Identified impact: Potential, direct or indirect, impact on the use of this frequency range by some networks of the UK NA Common Heritage. There is possible application to Regions 1 and 3, the same single-entry epfd limits to emissions radiated by non-GSO systems agreed at WRC-23 in Region 2 for the frequency band 17.3-17.7 GHz and, possible extension of the aggregated epfd limits to emissions radiated by non-GSO systems from the frequency band 17.8-18.6 GHz defined in Resolution 76 to the frequency band 17.3- 17.7 GHz. It is also possible to keep unchanged the other existing conditions applicable for FSS to Region 1 in the frequency band 17.3-17.7 GHz under consideration WRC-27 Implica tions for the ITSO Comm on Herita ge Agenda Item 1.5 • Studies on development of regulatory measures, and implementability thereof, to limit the unauthorized operations of non-geostationary-satellite orbit (non-GSO) earth stations in the fixed-satellite service (FSS) and mobile-satellite service (MSS) and associated issues related to the service area of non-GSO FSS and MSS satellite systems Identified impact: While there is a general understanding that unauthorized earth stations should be prevented from their deployment when no required license/authorization is provided, the specific measures to be implemented may risk deployment of current earth stations with very strict provisions, which ultimately may be applicable to NGSO and GSO systems. Avoidance of possible additional burden to authorizing administrations to issue explicit agreements. WRC-27 Implica tions for the ITSO Comm on Herita ge Agenda Item 7 Candidate Topics • Application of RR No. 4.4 to space/satellite services. Deficiencies in, and improvements to the advance publication, notification and recording procedures of the RR relating to frequency assignments to stations of space services to be operated under RR No. 4.4 • Restrain Repeated BIU/BBIU. The use of the same satellite or different satellites to repeatedly bring into use and bring back into use the same frequency assignments of a satellite network or system for a short period of time. • Repeated BIU/BBIU. Within 0.5 degrees of longitude of the physical satellite) without moving the satellite (“hop without move”) • Recording of frequency assignments in space services under RR No. 11.41 • Assessing the potential advantage to define coordination arc for some frequency bands above 3.4 GHz (or in the range 3.4 – 17 GHz) • Modifications of RR Appendix 4  WRC-27 Implica tions for the ITSO Comm on Herita ge Agenda Item 7 Candidate topics • Resolution 553 (Rev.WRC-23) (21.4-22 GHz frequency band. Not interest for ITSO. • Resolution 170 (Rev.WRC-23). Related to Appendix 30 B. Not related to frequency bands of CH • RR No. 11.44B/Capability • Inclusion of the territory of a country in the service area of a notified geostationary (GSO) satellite networks in the planned and unplanned BSS frequency bands and in the planned FSS frequency bands subject to Appendices 30A and 30B, without imposing new coordination restrictions to satellite networks already submitted to the Bureau • Unrealistic gain contours • Enhancing the responsibility of the notifying administration of a satellite network and/or system a) Designation of the responsible administration for a consolidated network or system; b) Enhancing the responsibility of the notifying administration for the actions of the satellite operator using the filed RF spectrum.  WRC-27 Implica tions for the ITSO Comm on Herita ge Agenda Item 9.2 - Inconsistencies Radio Regulations Identified Impact: Observe any potential impact of regulatory procedures applicable to the GSO C and Ku bands Agenda Item 9.3 - Report RRB.
