The EGNOS Safety of Life Service (SoL) consists of an augmentation signal to the Global Positioning System (GPS) Standard Positioning Service (SPS) intended for most transport safety critical applications. The target application domains are, thus, aviation, maritime, railway and road where degradation in the navigation system performance without a notice within the specified time to alert would endanger lives.
Terms and Conditions
The Safety of Life Service is accessible to any user equipped with an EGNOS certified receiver and located within the appropriate EGNOS SoL Service area.
However, navigation operations based on the EGNOS SoL Service require authorization issued by the relevant authority as long as the specific authority or applicable regulation states that no such authorization is required. This authorization, as defined in EGNOS Mission Requirements Document[1], is subjected to specified operational conditions and limitations, existence of published navigation procedure and to the certification of the on board navigation equipment.
Consequently, an aircraft or operator will need to be subscriber of the required Service Level Agreement in order to get a service guarantee from the EGNOS Service Provider on the EGNOS Safety of Life Service. In addition, the service guarantee will only be applicable within the Safety of Life Service area.
EGNOS SoL for Aviation
The SoL Service is intended to support a wide range of transport domains. Nevertheless, the main objective of the EGNOS SoL service is to support civil aviation operations down to Localizer Performance with Vertical guidance (LPV). This means that the service is compliant with aviation Approach with Vertical Guidance (APV-I) requirements defined in the ICAO Standard and Recommended Practices (SARPs) for SBAS[2] as expressed in EGNOS Safety of Life Service Definition Document.[3]
At the date of this publication, only the aviation domain has specific service requirements, as well as certification and individual authorization procedures developed and implemented.
On the 2nd March 2011, the European Satellite Services Provider (ESSP)[4] declared[5] the Safety-of-Life (SoL) signal officially available for aviation with the authorization of the European Commission (EC) to provide the service. At this point message type 0 (MT0) that used to transmit the same contents as a regular MT2 message before certification of EGNOS for civil aviation was removed.
