Source - EGNOS
Scope of this note
This note is the EGNOS child source note for the SBAS service-provider family. It records official EGNOS/EUSPA public signals for the EGNOS Safety of Life Service for Aviation and clearly separates those service-definition signals from equipment approval, procedure design, national AIP publication, and operational authorization.
Use this note for EGNOS-specific service-provider and Safety-of-Life service-definition claims. Use Source - SBAS Service Providers for cross-system routing. Use Source - EASA ETSO-C145e and ETSO-C146e for article-approval routing and Source - ICAO PANS-OPS Doc 8168 and Doc 9613 PBN Manual for procedure-design routing.

Extracted official EGNOS signals
The EGNOS Safety of Life Service Definition Document page states that EGNOS augments GPS L1 C/A by providing correction data and integrity information for improving positioning, navigation, and timing services over Europe, with future GPS/Galileo L1/L5 augmentation planned.
The same official page states that the EGNOS Safety of Life Service for Aviation is openly provided, freely accessible without direct charge, and tailored to safety-critical aviation applications.
The official page states that the service is compliant with aviation requirements for APV-I and Category I precision approaches as defined by ICAO Annex 10. It also states that operational use may require specific authorization by relevant authorities.
The service-document page describes the SDD’s purpose as giving information on the EGNOS SoL Service for Aviation, including system architecture, Signal-In-Space characteristics, performance achieved, and technical/organizational framework.
The extracted PDF summary reports these additional service-definition signals:
| Official/public signal | Extracted value or boundary |
|---|---|
| Service commitment scope | Provision of augmentation signal to GPS SPS with committed performance subject to SDD limitations and disclaimers |
| Intended users | Aviation users with EGNOS-certified receivers and organizations implementing EGNOS-based procedures, subject to competent authority approval where applicable |
| Service lifetime signal | Intended minimum 20-year provision from first declaration date, with 6 years advance notice for significant service changes |
| SoL declaration history | NPA/APV-I declared 2 March 2011; LPV-200 declared September 2015 in SDD v3.0 context |
| Service separation | ESMAS, Open Service, and EDAS are outside this aviation SoL SDD and are described in separate SDDs |
What this source can currently anchor
This note can currently anchor these EGNOS-specific statements:
- EGNOS is Europe’s SBAS and provides an aviation Safety of Life service definition through official EGNOS/EUSPA material.
- The EGNOS SoL Service for Aviation is described as openly provided and freely accessible without direct charge.
- Official EGNOS material describes the SoL service as tailored for safety-critical aviation applications and compliant with APV-I and Category I precision-approach requirements as defined by ICAO Annex 10.
- Official EGNOS material states that operational use may require authorization by relevant authorities.
- The 2024 in-force SDD page can anchor version/status metadata for the EGNOS SoL Service Definition Document.
What this source must not be used for yet
Do not use this note alone to publish:
- country-specific authorization, AIP publication, runway minima, or operator approval;
- EASA ETSO or receiver certification requirements;
- procedure-design requirements for LPV, LPV-200, or APV-I;
- exact real-time availability or continuity values outside the extracted SDD context;
- EGNOS superiority or interoperability claims not directly supported by official cross-provider material;
- EGNOS Open Service, EDAS, or maritime ESMAS claims beyond the fact that those services are separate SDD families.
