Source - ICAO Doc 9855
Scope of this note
This note records a standards-mapping correction. Earlier vault drafts treated ICAO Doc 9855 as if it were an SBAS technical-specification source. The ICAO Store public catalog identifies Doc 9855 as Guidelines on the Use of the Public Internet for Aeronautical Applications.
Important boundary:
- This note is based on public ICAO Store catalog metadata, not full manual extraction.
- It is sufficient to prevent the current vault from using Doc 9855 as an SBAS technical-specification source.
- Do not use Doc 9855 as the authority for SBAS architecture, LPV, integrity, protection levels, alert limits, performance testing, or service requirements.
Public-catalog identity signal
| Field | Current ICAO Store signal |
|---|---|
| Issuing body | ICAO |
| Document | Doc 9855 |
| Title | Guidelines on the Use of the Public Internet for Aeronautical Applications |

| Order/SKU signal | 9855 / DOC-09855-001-01 |
| SBAS relevance signal | No SBAS technical-specification role identified in the reviewed public catalog material |
Provenance correction
Previous in-vault wording mapped Doc 9855 to SBAS technical specifications. Treat that mapping as incorrect unless future direct source review identifies a narrow, non-SBAS internet/aeronautical-applications claim.
Appropriate current use:
- possible source for public-internet use in aeronautical applications, after direct extraction.
Inappropriate current use:
- SBAS system design;
- GPS/SBAS airborne equipment;
- LPV capability;
- protection-level and alert-limit definitions;
- SBAS performance monitoring;
- regional SBAS implementation claims.
