EGNOS Service Provider, ESSP, and the SEINÄJOKI Airport have recently signed an EGNOS Working Agreement (EWA), as another step for the implementation of EGNOS-based approach procedures (LPV SBAS procedures) across Finland.

As you know, EGNOS is the European Geostationary Navigation Overlay Service. It provides an augmentation signal to the Global Positioning System (GPS) Standard Positioning Service (SPS). The EGNOS service enables RNP APCH (Required Navigation Performance Approach) down to a minimum as low as 200 feet (~60 meters).

The agreement was signed on the 31st of May, 2019, and it establishes the operational and legal framework to use the EGNOS Safety-of-Life Service as a navigation aid between the EGNOS Satellite Services Provider – ESSP - and this airport interested in using this service.

This agreement is framed into the EU Space Program actions to get the highest security rates and accuracy systems in aviation through Satellite Based Navigation Protocol.

The signature of the EWA concludes an important step in international cooperation to employ EGNOS precision signals and services in Finland for a cost efficient navigation solution for the benefit of SEINÄJOKI Airport’s customers using precision air navigation in Finland.

Seinäjoki Airport is an airport in Ilmajoki, Finland, about 6 NM south-southwest of Seinäjoki city centre. The airport has been operated since 2016 by Seinäjoen Lentoasema Oy. Before that it was operated by Rengonharju-säätiö. 

ESSP SAS (European Satellite Services Provider) is a European private company under French law whose shareholders are 7 key Air Navigation Service Providers. ESSP acts as the service provider for EGNOS, the European Geostationary Navigation Overlay Service. The company is based in Toulouse (France) and Madrid (Spain).
