The European Geostationary Navigation Overlay Service (EGNOS) provides an augmentation service to the Global Positioning System (GPS) Standard Positioning Service (SPS). Presently, EGNOS augments GPS using the L1 (1575,42 MHz) Coarse/Acquisition (C/A) civilian signal function by providing correction data and integrity information for improving positioning, navigation and timing services over Europe. The EGNOS Safety of Life (SoL) Service is provided openly and is freely accessible without any direct charge, and is tailored to safety-critical transport applications in various domains, in particular for aviation applications. The service is thus compliant with the aviation requirements for Approaches with Vertical Guidance (APV-I) and Category I precision approaches1, as defined by ICAO in Annex 10 [RD-6]. The operational use of the EGNOS SoL Service may require specific authorisation by the relevant authorities in the application sectors concerned. This version of the “EGNOS SoL Service Definition Document” (EGNOS SoL SDD) is intended to give information on the EGNOS SoL Service. The document describes the EGNOS system architecture and Signal-In-Space (SIS) characteristics, the SoL service performance achieved, and provides information on the established technical and organisational framework, at European level, for the provision of this service. It is intended to be of use for Air Navigation Service Providers (ANSPs), receiver manufacturers, equipment integrators, airlines, operators, GNSS application developers and the final users of the EGNOS SoL Service. The document includes also complementary high level information on GNSS concepts, the GPS Service, the EGNOS System/Services, the EGNOS Management structure and EGNOS interfaces with users, as well as the minimum performance characteristics of the EGNOS SoL Service. This document is not intended to address EGNOS Open Service (OS) nor EDAS performance. Information about the EGNOS OS is available in a separate document called the “EGNOS Open Service - Service Definition Document” (EGNOS SDD OS - [RD-10]), whilst information regarding EDAS can be found in another separate document called the “EGNOS Data Access Service (EDAS) – Service Definition Document” (EDAS SDD – [RD-11]). This document will be updated in the future as required in order to reflect any changes and improvements to the EGNOS SoL Service.
