Our registry mirrors the authoritative source.
The International Telecommunication Union's Space Network System (SNS) is the authoritative global record of orbital slot filings and frequency coordination. Wavestar does not replace the SNS — we mirror it, reconcile it nightly, and expose it through signed attestations so that cleared spectrum and orbital-slot trades stand on verifiable ground.

What this covers
Coordination, notification, and the Plan appendices.
The ITU radiocommunication framework — under the Radio Regulations — covers three overlapping processes: advance publication, coordination, and notification. Our registry serves each process at the right layer.
- 01
Advance Publication (API) tracking
We track API filings submitted by member-state administrations on behalf of our clearing members. API metadata is ingested against the SNS schema and indexed on the did:orbit registry within 24 hours of publication in the ITU BR IFIC. - 02
Coordination requests and responses
Coordination filings (under Article 9 of the Radio Regulations) are tracked per administration, per satellite network, per frequency band. Responses are captured as signed registry entries, not free-text. - 03
Notification and MIFR entries
Notification filings leading to recording in the Master International Frequency Register (MIFR) are the authoritative spectrum-rights ground truth. Our registry records each MIFR entry with its signed ITU reference. - 04
Plan appendices — AP30 / AP30A / AP30B
For Plan-based services (broadcasting satellite, feeder links, fixed-satellite Plan), we track Plan appendix filings and modifications, reconciling against the published Plan at each WRC cycle. - 05
Bringing-into-use timelines
Seven-year bringing-into-use windows under RR No. 11.44 are tracked per filing. Expiry alerts surface to the member via Terminal six months and three months before the deadline. - 06
Cost-recovery fee tracking
ITU cost-recovery fees for processing satellite-network filings are tracked per filing. Fee status is a settlement precondition for any cleared trade referencing the underlying filing.
How reconciliation runs
One nightly reconciliation, one signed divergence report.
Each night a reconciliation job pulls the latest ITU BR IFIC and compares every relevant entry against our registry. Any divergence is an alert, not a warning.
- 02:00 UTCComplete
ITU BR IFIC ingestion
Scheduled pull of the latest BR IFIC as soon as published. XML parsed against the SNS schema; schema drift detected and escalated immediately if encountered. - 02:15 UTCComplete
Registry diff computed
Entry-by-entry diff between the authoritative ITU record and our registry. Additions, modifications, and deletions enumerated with the matching registry subject. - 02:30 UTCComplete
Signed divergence report
The diff report is canonicalised (JCS), signed by the registry service, appended to the transparency log, and anchored in the hourly Ethereum and Bitcoin anchors. - 03:00 UTCComplete
Stakeholder notifications
Clearing members whose active filings moved status overnight receive Terminal notifications and, where configured, email alerts — with the signed diff report attached.
Ongoing obligations
Between WRCs, there is no pause.
Public documents
Coordination outputs, versioned and signed.

Companion filing
FCC IBFS sits alongside ITU SNS.
Where ITU is the international authoritative source, the FCC International Bureau Filing System is the US-specific source for satellite authorisations. We reconcile both.
