- APT Members support to introduce power flux-density (pfd) and equivalent isotropically radiated power (e.i.r.p) limits in Article 21 of the Radio Regulations for satellite services (FSS, MSS, and BSS) to protect the fixed and mobile service, in the frequency bands 71-76 GHz and 81-86 GHz.
- APT Members propose to modify the Resolution 775 (WRC-19). If the Resolution is revised, the protection of mobile service should also be taken into account.
- APT Members do not support the WRC-27 preliminary agenda item 2.4 be included in the agenda of WRC-27. APT Members support this item be included in the preliminary agenda of WRC-31.

APT Common Proposal: Doc. WRC-23/62(Add.27)(Add.17)
- Issue 4: preliminary agenda 2.7
APT View:
APT Members do not support the inclusion of this preliminary item 2.7 in the agenda of WRC-27 and support the suppression of the Resolution 178 (WRC-19).
APT Common Proposal: Doc. WRC-23/62(Add.27)(Add.18)
- Issue 5: preliminary agenda 2.8
APT View:
APT Members do not support the inclusion of WRC-27 preliminary agenda item 2.8 in the agenda of WRC-27 and support the suppression of Resolution 249 (WRC-19).

- Issue 8: non-GSO FSS in 51.4-52.4 GHz
APT View: None
APT Common Proposal: None
- Issue 9: MSS allocations below 4 GHz
APT View: None
APT Common Proposal: None
- Issue 10: Review of sharing conditions in the 13.75-14 GHz band
APT View:
APT Members support to update the FSS earth station limitations under RR No. 5.503 by reviewing the usage and sharing conditions of the frequency band 13.75-14 GHz that will reduce the mismatch between the usage of the uplink and downlink FSS bands within the 10-15 GHz frequency range.
APT Members note that there has been no change to protection requirements for the radiolocation service and thus do not support the relaxation of the limits set out in RR No. 5.502 unless the same level of protection as afforded to the radiolocation in the current RR No. 5.502 is ensured.
On that condition, APT Members supports the review the usage and sharing conditions of the band 13.75-14 GHz to enable efficient use of the band by uplink FSS earth stations with smaller antenna sizes for consideration at WRC-31.
APT Common Proposal: Doc. WRC-23/62(Add.27)(Add.21)
- Issue 11: non-GSO sharing with GSO in 11/14 and 20/30GHz
APT View: None
APT Common Proposal: None
- Issue 12: Regulatory framework for non-GSO FSS to protect GSO FSS/BSS
APT View:
APT Members are of the view that it is necessary to conduct studies to ensure the compatibility between non-GSO FSS and MSS systems in the frequency bands which Resolution 35 (WRC-19) apply, taking into account the long-term sustainability, the equitable access, and rational and compatible use of the non-GSO orbital and spectrum resources consistent with the objectives of Article 44 of the Constitution and the Resolution 219 of the Plenipotentiary Conference 2022 by Radiocommunication Assembly and a future competent WRC.
