Summary

  • China has proposed a new PP-26 resolution to study voluntary identity broadcasts from satellites and to consider the issue for the 2031 World Radiocommunication Conference agenda. This is a proposal, not an adopted radio rule.
  • ITU already assigns an itu_sat_id inside satellite filing data. The proposed broadcast would address the missing link between a signal received from orbit and the network filing in the registry; it would grant no new filing priority.

An observer can see a satellite in orbit. The hard part is asking the radio signal which ITU network filing owns it. China's new PP-26 draft, posted by the ITU on 1 November, says today's transmitted signals do not supply that association. It proposes studying a satellite broadcast of its own identity, receivable by an administration or operator with suitable equipment even without a frequency-coordination relationship.

The database side of the bridge already has a name. The Radiocommunication Bureau's identifier note defines itu_sat_id in the SNS V10 filing database as notice ID, orbital-plane ID and satellite sequence number joined in one value. Resolution 8 and 35 submissions link individual space stations to that field. Before a notification is published, an administration may use a temporary ID; the Bureau says some older converted links will be corrected when better Resolution 8 information arrives. That is a working register, with updates, rather than a label permanently bolted to a spacecraft.

China's draft asks ITU-R study groups to test the technical and regulatory feasibility of a voluntary broadcast. The studies would decide the medium and format, possible fields such as the filing reference, satellite ID and administration or operator, how those fields relate to the Master International Frequency Register, and how the signal would coexist with existing allocations and harmful-interference protections. The draft urges consideration of the issue on the 2031 World Radiocommunication Conference agenda; the Council would still have to place it there.

Member States are invited to consider voluntary use in networks under their jurisdiction.

This is where the proposed beacon must earn trust. Hearing a claimed filing reference would be useful only if a receiver can bind it to the current ITU record, including temporary IDs and later corrections. The draft does not specify the verification method. A published receiver-to-registry matching design would turn the attractive name-tag idea into a testable identification system.

China also keeps the legal line clear: a broadcast would create no new filing right or priority and would not change the status of an assignment in the MIFR. The radio signal could help identify the subject of an interference case; it could not by itself rewrite the registry's order of rights.
