APT WTDC-25 COORDINATION

to consider possible changes, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, on advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate the rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit

Topic A: Tolerances for Certain Orbital Characteristics of Non-GSO Space Stations in the FSS, BSS and MSS

APT View:

• APT Members support the development of the definition of tolerances of non-geostationary-satellite orbit (non-GSO) space stations in the FSS, BSS and MSS with frequency assignments subject to Resolution 35 (WRC-19). APT Members support the development of these tolerances in the context of ITU regulatory procedures such as bringing into use (BIU), bringing back into use (BBIU) and the milestone-based approach.
• APT Members are of the view that the development of the definition of tolerances of non-GSO space stations in the FSS, BSS and MSS, should be limited to the inclination of the orbital plane, the altitude of the apogee of the space station, the altitude of the perigee of the space station and the argument of the perigee of the orbital plane, to account for potential differences between the notified and deployed orbital characteristics.
• APT Members are also of the view that appropriate regulatory consequences/measures should be developed under Nos. 11.44C, 11.49.2 and 11.51, taking into account the operational aspects of the non-GSO space stations in the FSS, BSS and MSS with frequency assignments subject to Resolution 35 (WRC-19), if the operations are beyond the specified allowable tolerances. These regulatory measures should be implementable and not have any retroactive application. Moreover, necessary transitional measures for application of the decision of WRC-23 may need to be developed.
• APT Members do not support over regulation nor regulatory methods that are too stringent and inflexible, to allow the operation of existing and new satellites with the possibility to make adjustments to them, in order to comply with the established orbital tolerances.
• For frequency assignments of non-GSO systems in the FSS, BSS and MSS subject to Resolution 35 (WRC-19) notified prior to the entry into force of the Final Acts of WRC-23, APT Members support allowing an update to the notified orbital parameters within a reasonable range, based on the conditions of the new draft Resolution, in order to align with the actual deployed characteristics, without changing the date of receipt of the associated notice.
• APT Members support Method A2 Option A of the CPM Report.

APT Common Proposal:  Doc. WRC-23/62(Add.22)(Add.1)

to consider possible changes, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, on advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate the rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit

Topic B: Post-milestone reporting procedure for non-GSO systems

APT View:

• APT Members support the development of the post-milestone procedures for non-GSO satellite systems in FSS, BSS and MSS subject to Resolution 35 (WRC-19).
• APT Members are of the view that the studies for developing final post-milestone procedures at WRC-23 need to take into account the reporting procedure defined in resolves 19 of Resolution 35 (WRC-19).
• APT Members support the adoption of a new Resolution to replace resolves 19 of Resolution 35 (WRC-19) at WRC-23, suppressing resolves 19 of Resolution 35 (WRC-19) and leaving the rest of the Resolution 35 (WRC-19) as is otherwise.
• APT Members are also of the view that when developing the post-milestone procedures, over regulation needs to be avoided and some degree of operational flexibility which is necessary for the maintenance of the non-GSO system in the FSS, BSS and MSS, may need to be duly considered.
• APT Members also support the development of appropriate regulatory measures for frequency assignments to non-GSO space stations that do not comply with the post-milestone requirements/procedures.
• APT Members support Method B2 with preference for Option B2b of the CPM Report.

Topic C: 7/8 and 20/30 GHz GSO MSS protection

APT View:

• APT Members support protection of GSO satellite networks in the mobile-satellite service operating in the 7/8 GHz and 20/30 GHz bands from emissions of non-GSO satellite systems operating in the same frequency bands and identical directions, by means of appropriate regulatory solutions.
• APT Members support extending the application of concept of provisions of RR No. 22.2 for the protection of geostationary-satellite networks in the mobile-satellite service operating in the bands 7/8 GHz and 20/30 GHz from emissions of non-geostationary-satellite networks.
• APT Members support Method C3 in the CPM Report to address this topic.

Topic E: Improved procedures under RR Appendix 30B for new ITU Member States

APT View:

• APT Members support granting new ITU Member States the same right as those granted to other Member States in Appendix 30B, based on principles stipulated in Article 44 of the Constitution, Resolution 2 (Rev.WRC-03) and those contained in Article 1 of AP30B.
• APT Members support technical assessments of the interference scenarios for new ITU Member States so that the possible solution, does not affect the existing allotments in the Plan and assignments in the List of Appendix 30B.
• APT Members are of the view that there is a need to find a suitable solution, to tackle the difficulties of administrations in applying Article 7, for new ITU Member State to obtain a national allotment, without one national allotment having to conduct inconclusive bilateral coordination with other administrations.
• APT Members are further of the view that, in case that an overall solution is not found, it is recommended to find a workable solution on a case-by-case basis, which could be compatible with allotments in the Plan and assignments in the List of Appendix 30B, to meet the interference criteria defined in § 1.4 of Annex 1 to Appendix 30B for this new ITU Member State.

APT Common Proposal: None

Marrakesh, 2002) of the Plenipotentiary Conference, on advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate the rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit

Topic F: Exclusion of feeder-link/uplink service & coverage areas in AP30A/30B

APT View:

• APT Members support the exclusion of the territory of a country from the service area of feeder link of another country and the adjustment of coverage area to the smallest to be aligned with the service area of feeder link under RR AP 30A.
• APT Members support developing specific measures to avoid creating obstacles to those administrations wishing to establish satellite networks of RR AP 30B over their territories, taking into account the roll-off of the receiving beams of adjacent satellite networks. Further studies on the adjustment of the coverage area to the smallest to be aligned with the service area of the RR AP 30B submissions under consideration is required, since the alignment of the coverage area with the service area may not be always feasible, especially when the satellite network is already in operation.
• APT Members do not support Method F1 of the CPM Report.
