EGNOS
Scope status
This page is a source-routed system note for EGNOS, Europe’s SBAS implementation and aviation Safety of Life service family.
The verified EGNOS-specific claims on this page route to Source - EGNOS. Cross-system provider context routes to Source - SBAS Service Providers. Article approval, procedure design, and operational authorization are intentionally separated.
Boundary:
- This page does not publish country/runway-specific EGNOS procedure availability or minima.
- This page does not treat EGNOS SoL service definition as aircraft, receiver, operator, or national operational authorization.
- This page does not duplicate detailed SDD excerpts; those belong in Source - EGNOS.
Working definition
EGNOS is the European Geostationary Navigation Overlay Service, Europe’s satellite-based augmentation system. Official EGNOS Safety of Life Service Definition material describes the aviation SoL service as augmenting GPS L1 C/A through correction data and integrity information for safety-critical aviation applications.
Official source signals
| Signal type | Current authenticated source-routed statement |
|---|---|
| System identity | EGNOS = European Geostationary Navigation Overlay Service; routed to Source - EGNOS |
| Service document | EGNOS Safety of Life Service Definition Document, Version 03-06 / Issue 3.6, published 2024-09-09 and marked In Force |
| Service scope | Official EGNOS material describes the SoL Service for Aviation as openly provided, freely accessible without direct charge, and tailored to safety-critical aviation applications |
| ICAO requirement context | Official EGNOS material states that the service is compliant with APV-I and Category I precision-approach requirements as defined by ICAO Annex 10 |
| Authorization boundary | Official EGNOS material states that operational use may require specific authorization by relevant authorities |
Relationship to civil aviation use
EGNOS matters in this KB because it connects European service-provider material to:
- EASA article-approval routing in Source - EASA ETSO-C145e and ETSO-C146e;
- ICAO SARPs routing in Source - ICAO Annex 10 Volume I GNSS SBAS;
- PBN/procedure-design routing in Source - ICAO PANS-OPS Doc 8168 and Doc 9613 PBN Manual;
- operational deployment questions that must later be resolved through regulator, ANSP, and AIP material.
Claims intentionally not duplicated here
To prevent overlapping knowledge, this page does not reproduce the EGNOS SDD’s service-area, architecture, performance, liability, or user-obligation detail. Those details belong in Source - EGNOS and any later direct-extraction child notes.

Open verification questions
- Which current official EGNOS/ESSP source should be used for live performance/status claims?
- Which national AIP/ANSP sources should be used for country-specific EGNOS procedure deployment?
- Which EGNOS service documents should be extracted if Open Service, EDAS, or maritime ESMAS enters the KB scope?
