The agreement will enable the publication of EGNOS-based approach procedures in the main Slovenian airports currently being acted by SLOVENIA CONTROL: LJUBLJANA / BRNIK (LJLJ), MARIBOR / OREHOVA VAS (LJMB), PORTOROZ / SECOVLJE (LJPZ) and CERKLJE / CERKLJE OB KRKI (LJCE)

The EGNOS Working Agreement (EWA), signed by EGNOS Service Provider (ESSP) and SLOVENIA CONTROL, represents a key first step towards the implementation of EGNOS-based approach procedures at the major Slovenian airports.

This agreement, in accordance with European rules, will allow the publication of EGNOS-based approach procedures and it is foreseen that SLOVENIA CONTROL will officially publish their first LPV approach in 2021 after NCA approval.

PORTOROZ / SECOVLJE (LJPZ) airport is expected to be the first to implement RNP approaches with the three minimas in order to comply with Regulation (EU) 2018/1048, the so called PBN IR.

“The reason for these implementations is the modernization and availability of PBN procedures at all international airports in Slovenia in compliance with EU Regulation” said Jure Novak, Senior Technologist in ATS Department from Slovenia Control."

This EWA agreement was signed in June 2020, and it establishes the operational and legal framework to use the EGNOS Safety-of-Life Service as a navigation aid between the EGNOS Service Provider – ESSP - and the Airport / Navigation entity willing to use this service.

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).

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

The signing of the EWA agreement concludes an important step in international cooperation to employ EGNOS precision signals and services in Slovenia for a cost-effective precision air navigation solution.

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).
