EGNOS Data Access Service

The EDAS-N project examines how the current EGNOS Data Access Service (EDAS) should evolve to meet user needs between 2020 and 2030. On the basis of its analysis, it proposes 8 new EDAS services.

EGNOS (European Geostationary Navigation Overlay Service) provides augmentation to the Global Positioning System (GPS) Standard Positioning Service (SPS) since 2011. EGNOS augments GPS by using the L1 (1,575.42 MHz) Coarse/ Acquisition (C/A) civilian signal function, which broadcasts correction data and integrity information for positioning and navigation applications over Europe.

EGNOS provides three services:

• Safety of Life (SoL) Service, which is intended for transport applications in areas where lives could be endangered if the performance of the navigation system is degraded below specific accuracy limits without alerting the user within a specified time.
• Open Service (OS), which provides timing and positioning services to any user equipped with an appropriate GPS/SBAS compatible receiver.
• EGNOS Data Access Service (EDAS), which is intended for users who require EGNOS products for commercial and professional use.

EDAS provides data from EGNOS' ground infrastructure to promote the development of applications for professional and commercial use. The next generation of EGNOS – EGNOS V3 – will augment the GPS and Galileo satellite constellations in the L1 and L5 bands. It will also extend the service area to cover the entire EU.

Objectives

The EDAS-N project defines the potential evolution of EDAS between 2020 and 2030. As EDAS is expected to disseminate EGNOS V3 data over this period, the analysis focuses on what additional features could help generate new EDAS services for users and service providers.

The EDAS-N project defined how the current EGNOS EDAS should evolve to meet more demanding user needs between 2020 and 2030. The analysis looked at potential new EDAS services and their market uptake. It also estimated their capital expenditure and operating expense. The project proposed a final set of 8 new EDAS-based services, and defined their implementation schedule.

The uptake of the next generation of EDAS is estimated at 178 direct users (mainly service providers) and 350,000 indirect users by 2030.
