The new EGNOS Safety-of-Life Service Definition Document, published by the European GNSS Agency (GSA), highlights the service’s extended coverage area. 

The GSA has published an updated EGNOS Safety-of-Life (SoL) Service Definition Document (SDD), which is now available to EGNOS users. A highlight of the new SDD is the significant extension to the declared service area that has been achieved since the last update in 2016. Overall, the service area has increased by 25%, with a substantial increase in coverage over Norway, Sweden and Finland and a slight increase over central Romania and north-east Bulgaria. 

Improved availability of LPV-200

This extension in coverage equates to an important improvement in LPV-200 (Localizer Performance with Vertical guidance) availability. First declared in 2015, LPV-200 delivers accurate information on an aircraft’s approach to a runway with the use of GNSS positioning technology. The result is lateral and angular vertical guidance without the need for visual contact with the ground until an aircraft is 200 feet above the runway.  Today there are 150 LPV-200 procedures published across Europe and 434 instrumental runway ends with published LPV/LPV-200 procedures, representing 35% of all European instrumental runway ends. 

Additional clarifications and updates

The updated SDD clarifies use for non-EU and non-ATS cases, showing that it’s not only ANSPs that can benefit from EGNOS, but also aerodrome and rotocrafts operators. In addition, the SDD describes the characteristics and conditions of access to the EGNOS SoL service, along with providing information about the EGNOS system architecture, Single-in-Space (SIS) characteristic, service performance achieved, and EGNOS user interfaces.
